64 kesitli multidedektör BT ile pulmoner emboli tespit edilen hastalarda eş zamanlı yapılan BT venografi ile alt ekstremite venöz renkli doppler usg korelasyonu
(Selçuk Üniversitesi Tıp Fakültesi, 2010) Nayman, Alaaddin; Ödev, Kemal
Pulmoner tromboemboli (PTE) sık görülmekle birlikte tanısındaki gecikmenedeniyle mortalitesi yüksek bir hastalıktır. PTE ve alt ekstremite derin ven trombozu (DVT) aynı patolojik sürecin iki parçası olmakla birlikte PE'nin %90 nedenini alt DVT oluşturmaktadır. Çalışmamızın amacı klinik muayenesinde pulmoner emboli ön tanılı olgularda BTA' nın tanıya katkısını, alt ekstremite derin venlerinin indirekt BT venografi ve RDUS ile değerlendirilmesi ve son iki incelemenin DVT tanısındaki yerini araştırmaktır. GEREÇ VE YÖNTEM: Çalışmaya ön tanısında PE olan ve pulmoner BT anjiografide (BTA) PE tespit edilen 46 hasta dahil edildi. Hastaların iliak krestler ile femur başı arası ve popliteal bölgeleri (kesit aralığı 0.8 mm) toplam bir bölge için 17-18 kesit alınacak şekilde, ek kontrast madde verilmeden tarandı. Hastalara aynı gün içinde alt ekstremite venlerine yönelik RDUS yapıldı. BULGULAR: Çalışma dahilindeki 46 hastanın 4' ünde RDUS' de trombüs varken BTV normaldi. 2' sinde de doppler normal iken BTV' de trombüs görünümü vardı. RDUS altın standart kabul edildiğinde indirekt BTV'nin duyarlılığı: %81.8 seçiciliği: %91.6 olarak hesaplandı. İki tetkik arasında Kappa değeri: 0.738 olarak hesaplandı ve %87 tutarlılık olduğu saptandı. BTA çekimi için hastaya verilen ortalama doz miktarı 2.43 mSv, BTV için verilen doz 0.457 olarak hesaplandı. SONUÇ: Kombine BTA-indirekt BTV yöntemi olarak adlandırılan inceleme tekniğinde çok yüksek duyarlılıkta olmasa bile yüksek seçicilik oranında, düşük dozda ek kontrast madde verilerek DVT saptanabilmektedir.
AMYAND'S HERNIA: ULTRASONOGRAPHY FINDINGS
(ELSEVIER SCIENCE INC, 2016) Guler, Ibrahim; Alkan, Ender; Nayman, Alaaddin; Tolu, Ismet
Background: Amyand's hernia is described as the presence of an appendix vermiformis in the inguinal hernia sac. The incidence of Amyand's hernia is approximately 1% of all inguinal hernias. Amyand's hernia is diagnosed intraoperatively or preoperatively with radiologic examinations. Case Report: Two cases of Amyand's hernia, with and without acute appendicitis, are reported here. Why Should an Emergency Physician Be Aware of This? Amyand's hernia is a rare entity, and physical signs, laboratory results, and symptoms are not always helpful in diagnosis. Preoperative diagnosis of Amyand's hernia is not straightforward, and is generally an incidental finding during surgery. Imaging modalities, including ultrasound, can be very useful for making this rare diagnosis. (C) 2016 Elsevier Inc.
Application of first-pass contrast bolus tracking sequence for the assessment of morphology and flow dynamics in cardiac MRI
(AVES, 2013) Paksoy, Yahya; Ozbek, Orhan; Gumus, Serter; Koc, Osman; Nayman, Alaaddin; Kerimoglu, Ulku
PURPOSE There are two well-known indications for first-pass perfusion in the literature. First is the evaluation of Myocardial ischemia, and the other is the evaluation of tumor vascularity. Our aim was to assess the value of a first-pass Contrast bolus tracking sequence (FPCBTS) for cases unrelated to these pathologies. MATERIALS AND METHODS A total of 35 patients (age range, 1 day to 66 years; mean age, 10.4 +/- 19.2 years; median age, 4.5 months) with suspected congenital (n=31) and acquired (n=4) heart and great vessel disease Were included in the study. All the patients underwent cardiac magnetic resonance imaging (MRI) and FPCBTS, and 20 patients underwent contrast enhanced magnetic resonance angiography (CE-MRA). We used cardiac MRI and CE-MRA for anatomic evaluation and FPCBTS for dynamic flow evaluation. RESULTS Truncus arteriosus, double outlet right ventricle, tetralogy of Fallot; corrected transposition of great arteries, atrial and ventricular septal defect, aortic rupture, cardiac hydatid cyst, tricuspid atresia, anomalous pulmonary venous return; and interrupted aorta were detected using the technique described here. Septal defects in six patients arid atrial aneurysm in two patients were excluded. The shunt gap and flow direction of the septal defects, a ruptured Wall in a dissected aorta, a hydatid cyst, and the atrial relationship in two cases with paracardiac masses Were diagnosed easily using this dynamic evaluation technique. CONCLUSION FPCBTS Can be performed in addition to cardiac MRI and CE-MRA to reveal flow dynamics and morphology.
Comparison Between Prospectively Electrocardiogram-Gated High-Pitch Mode and Retrospectively Electrocardiogram- Gated Mode for Dual-Source CT Coronary Angiography
(INT SCIENTIFIC INFORMATION INC, 2015) Koplay, Mustafa; Celik, Mahmut; Avci, Ahmet; Erdogana, Hasan; Demir, Kenan; Sivri, Mesut; Nayman, Alaaddin
Background: We aimed to report the image quality, relationship between heart rate and image quality, amount of contrast agent given to the patients and radiation doses in coronary CT angiography (CTA) obtained by using high-pitch prospectively ECG-gated "Flash Spiral" technique (method A) or retrospectively ECG-gated technique (method B) using 128x2-slice dual-source CT. Material/Methods: A total of 110 patients who were evaluated with method A and method B technique with a 128x2-detector dual-source CT device were included in the study. Patients were divided into three groups based on their heart rates during the procedure, and a relationship between heart rate and image quality were evaluated. The relationship between heart rate, gender and radiation dose received by the patients was compared. Results: A total of 1760 segments were evaluated in terms of image quality. Comparison of the relationship between heart rate and image quality revealed a significant difference between heart rate <60 beats/min group and >75 beats/min group whereas <60 beats/min and 60-75 beats/min groups did not differ significantly. The average effective dose for coronary CTA was calculated as 1.11 mSv (0.47-2.01 mSv) for method A and 8.22 mSv (2.19-12.88 mSv) for method B. Conclusions: Method A provided high quality images with doses as low as <1 mSv in selected patients who have low heart rates with a high negative predictive value to rule out coronary artery disease. Although method B increases the amount of effective dose, it provides high diagnostic quality images for patients who have a high heart rate and arrhythmia which makes it is difficult to obtain images.

(2013) Nayman, Alaaddin; Ödev, Kemal
Pulmoner tromboemboli (PTE) sık görülmekle birlikte tanısındaki gecikme nedeniyle mortalitesi yüksek bir hastalıktır. PTE ve alt ekstremite derin ven trombozu (DVT) aynı patolojik sürecin iki parçası olmakla birlikte PTE nin %90 nedenini alt ekstremite DVT oluşturmaktadır. Bu çalışmanın amacı pulmoner BT anjiografide (BTA) PTE tespit edilen olgularda, alt ekstremite derin venlerinin indirekt BT venografi (BTV) ve RDUS ile değerlendirilmesi ve son iki incelemenin DVT tanısındaki yerini araştırmaktır. Prospektif olarak, Haziran 2009 ve mayıs 2010 tarihleri arasında, ön tanısında PTE olan ve pulmoner BTA de PTE tespit edilen 46 hasta çalışmaya dahil edildi. Pulmoner BTA sonrasında indirekt BTV incelemesi ayrı iki bölge (iliak krestler-femur başı arası ve popliteal bölge) alınarak, ek kontrast madde verilmeden yapıldı. Hastalar aynı gün içinde alt ekstremite venlerine yönelik renkli doppler ultrasonografi (RDUS) ile değerlendirildi. Hastaların aldığı radyasyon dozları hesaplandı. Çalışma dahilindeki 22 erkek (ortalama yaş: 48,7) ve 24 kadın (ortalama yaş: 63,4) toplam 46 hastanın tümünde PTE vardı. 46 hastanın 22 sinde RDUS de DVT saptanmış olup 4 hastada RDUS de trombüs varken BTV normaldi. 2 hastada da RDUS normal iken BTV de trombüs görünümü vardı. RDUS altın standart kabul edildiğinde indirekt BTVnin duyarlılığı: %81.8 seçiciliği: %91.6 olarak hesaplandı. İki tetkik arasında Kappa değeri: 0.738 olarak hesaplandı ve %87 tutarlılık olduğu saptandı. BTA çekimi için hastanın aldığı ortalama radyasyon dozu 2.43 mSv, indirekt BTV için verilen ek radyasyon dozu ise 0.457 mSv olarak hesaplandı. Kombine BTA-indirekt BTV yöntemi olarak adlandırılan inceleme tekniğinde çok yüksek duyarlılıkta olmasa bile yüksek seçicilik oranında, düşük dozda ek radyasyon verilerek DVT saptanabilmektedir.
Diagnostic efficacy of diffusion-weighted MRI for pre-operative assessment of myometrial and cervical invasion and pelvic lymph node metastasis in endometrial carcinoma
(WILEY-BLACKWELL, 2014) Koplay, Mustafa; Dogan, Nasuh Utku; Erdogan, Hasan; Sivri, Mesut; Erol, Cengiz; Nayman, Alaaddin; Karabagli, Pinar
Introduction: To determine the diagnostic accuracy of diffusion-weighted magnetic resonance imaging (DW-MRI) for the pre-operative assessment of patients with endometrial carcinoma and to assess myometrial and cervical invasion as well as pelvic lymph node metastasis. Methods: Fifty-eight women who underwent surgery for histopathologically confirmed endometrial carcinoma were included in the current study. Prior to surgery, patients were evaluated using pelvic DW-MRI and gadolinium-enhanced T1-weighted imaging (Gd-T1WI). Gd-T1WI was evaluated together with T2-weighted images. DW-MR images were obtained in the axial plane using echo-planar spin-echo pulse sequences with different b factors. Endometrial carcinomas were observed as areas of increased intensity on DW-MRI images, and their intensity was compared with the surrounding hypo-intense myometrium. Pre-operative DW-MRI and Gd-T1WI results were compared with post-operative histopathological findings that served as reference standards. Results: The sensitivity, specificity, positive (PPV) and negative predictive values (NPV), and diagnostic accuracy of DW-MRI for differentiation between superficial myometrial invasion and deep myometrial invasion were 85%, 89%, 81%, 92% and 88%, respectively. The sensitivity, specificity and diagnostic accuracy rates were 82%, 91% and 89.6% for cervical invasion and 100%, 96% and 96.5% for pelvic lymph node metastasis, respectively. The sensitivity, specificity, PPV and NPV, and diagnostic accuracy of Gd-T1WI for differentiation between superficial myometrial invasion and deep myometrial invasion were 85%, 81.5%, 71%, 91% and 83%, respectively. The sensitivity, specificity and diagnostic accuracy were 73%, 89% and 86% for cervical invasion, respectively. Conclusions: These findings suggest that DW-MRI may be a good diagnostic tool with high sensitivity and specificity for assessing myometrial invasion and detecting tumour extension. We suggest that DW-MRI should be considered as a routine part of the pre-operative pelvic MRI in all patients with endometrial carcinoma.
Does median nerve translate pre- and postoperatively in carpal tunnel syndrome?
(TURKISH JOINT DISEASES FOUNDATION, 2018) Yildirim, Ahmet; Tutar, Onur; Nayman, Alaaddin; Yalcin, Levent; Altan, Egemen
Objectives: This study aims to evaluate the distance between the median nerve and the hook of the hamate pre- and postoperatively in patients with carpal tunnel syndrome and to investigate the efficiency of magnetic resonance imaging in diagnosis and postoperative follow-up. Patients and methods: Median nerve decompression was performed by releasing the carpal tunnel in 15 patients (4 males, 11 females. mean age 51 years; range, 41 to 66 years) with carpal tunnel syndrome. The shortest distance between the median nerve and the hook of the hamate was measured with magnetic resonance imaging preoperatively and at three months after the operation and radial and ulnar translations were assessed. Findings were compared to those of a control group of 15 subjects (5 males, 10 females; mean age 52.2 years; range, 40 to 65 years). Results: Median nerve shifted ulnarwards in patients with carpal tunnel syndrome. An intragroup evaluation of five patients with thenar atrophy revealed that as disease severity increased, the degree of the nerve's medial translation increased. Compared to preoperation, the median nerve significantly shifted to the radial side after decompression. Conclusion: In carpal tunnel syndrome patients, we observed significant ulnar translation of the median nerve and lateral translation after releasing the carpal tunnel. Magnetic resonance imaging may be used to establish a diagnosis and to assess operation success in advanced carpal tunnel syndrome patients who may recover slowly postoperatively.
The effect of the presence of the accessory maxillary ostium on the maxillary sinus
(SPRINGER, 2016) Yenigun, Alper; Fazliogullari, Zeliha; Gun, Cihat; Uysal, Ismihan Ilknur; Nayman, Alaaddin; Karabulut, Ahmet Kagan
This study was conducted to investigate the presence of the accessory maxillary ostium and its effects on the maxillary sinus, and the concurrent occurrence of morphological variations of neighboring anatomical structures. This study was performed in a tertiary referral center. This is a cross-sectional retrospective study that evaluated coronal CTs of patients to determine the frequency of the accessory maxillary ostium and investigated any simultaneous morphological variations in ostium (AMO) plus any concurrent morphological variations of neighboringneighboring anatomical structures. The presence of the accessory maxillary structures were investigated in 377 patients, with 754 sides. AMO was found to be present in 19.1 % (72/377) of the patients. A concurrent mucus retention cyst was found to be statistically significant on both sides (right side: p = 0.00, left side: p = 0.00), as well as mucosal thickening (right side: p = 0.00, left side: p = 0.00), and maxillary sinusitis (right side: p = 0.04, left side: p = 0.03). No other concurrent variations of statistical significance were detected in the neighboring structures. Our study demonstrated that with the presence of AMO, the likelihood of encountering a mucus retention cyst (48.6 %) had an approximately threefold increase, and that of encountering mucosal thickening (43.0 %) and maxillary sinusitis (29.1 %) had a twofold increase.
The effect of the trendelenburg position on the internal jugular vein's cross-sectional area in overweight and obese children
(E-CENTURY PUBLISHING CORP, 2016) Sekmenli, Tamer; Nayman, Alaaddin; Onal, Ozkan; AriYuca, Sevil; Apiliogullari, Seza; Ciftci, Ilhan; Celik, Jale Bengi
Background: The Trendelenburg position is a common technique used during internal jugular vein (IJV) cannulation in pediatric patients. There has been some speculation as to the correlation between Trendelenburg positioning and increases in the cross-sectional area (CSA) of the IJV in obese child patients. In the present study, we use ultrasound (US) measurements to assess and determine the predictivity of Trendelenburg positioning on the CSA of the right IJV in obese child patients. Methods: The researchers of this studyenrolled 30 cases from the American Society of Anesthesiologists (ASA) II of patients under the age of 18 who underwent ultrasonographic examination between December 2013 and March 2015. US images of the right IJV of each patient were obtained in a transverse orientation at the cricoid level. The CSAs of the right IJVs were measured undert wo different conditions applied in a random orderin a sealed envelope: State 0, in which the table was flat (no tilt) and the patient lay in the supine position; and State T, in which the operating table wastilted 20 degrees to the Trendelenburg position. Results: The change in the CSA of the IJV from the supine to the Trendelenburg position (0.99 cm(2) vs 0.96 cm(2)) was not significant. In contrast, the CSA of the right IJV decreased in 14 of the 30 patients (9 of the 14 were female). Conclusions: The Trendelenburg position does not cause the mean CSA of the right IJV in obese child patients to increase; in fact, the position causes the CSA in some patients to decrease. The researchers of this study do not support the use of the Trendelenburg position for IJV cannulation in obese child patients.
The effectiveness of trendelenburg positioning on the cross-sectional area of the right internal jugular vein in obese patients
(PROFESSIONAL MEDICAL PUBLICATIONS, 2015) Onal, Ozkan; Apiliogullari, Seza; Nayman, Alaaddin; Saltali, Ali; Yilmaz, Huseyin; Celik, Jale Bengi
Objective: Trendelenburg positioning is a common approach used during internal jugular vein (IJV) cannulation. No evidence indicates that Trendelenburg positioning significantly increases the cross-sectional area (CSA) of the IJV in obese patients. The primary aim of this study was to determine the effectiveness of Trendelenburg positioning on the CSA of the right internal jugular vein assessed with ultrasound measurement in obese patients. Methods: Forty American Society of Anesthesiologists II patients with body mass index >= 30 kg/m(2) undergoing various elective surgeries under general endotracheal anesthesia were enrolled. Ultrasound images of the right IJV were obtained in a transverse orientation at the cricoid level. We measured the CSA of the right IJV two different conditions in a sealed envelope were applied In random order: State 0, table flat (no tilt), with the patients in the supine position, and State T, in which the operating table was tilted 200 to the Trendelenburg position. Results: The change in the CSA of the IJV from the supine to the Trendelenburg position (1.80 cm(2) vs 2.08cm(2)) was not significantly different. The CSA was paradoxically decreased in 10 of 36 patients when the position changed from State 0 to State T. Conclusions: Trendelenburg positioning does not significantly increase the mean CSA of the right IJV in obese patients. In fact, in some patients, this position decreases the CSA. The use of the Trendelenburg position for IJV cannulation in obese patients can no longer be supported.
Effects of body mass index, mesenteric and abdominal subcutaneous adipose tissue on the spinopelvic parameters
(SPRINGER WIEN, 2015) Uysal, Emine; Paksoy, Yahya; Koplay, Mustafa; Nayman, Alaaddin; Gumus, Serter
The purpose of this study was to investigate the effects of body mass index (BMI), thickness of the abdominal subcutaneous adipose tissue (ASAT), thickness of the mesenteric adipose tissue (MAT), weight and height on spinopelvic parameters. A total of 400 patients presented to the radiology department for whole abdominal computed tomography were included in the study. Patients' weight and height were measured to calculate BMI. Thickness of ASAT and MAT, lumbosacral angle (LSA), sacral slope (SS), pelvic tilt (PT), and pelvic incidence (PI) were measured from the images obtained. We analyzed the effects of BMI, ASAT, and MAT on spinopelvic parameters. In addition, patients included in the study were screened for isthmic spondylolisthesis and transitional vertebrae. Statistical analysis was carried out using SPSS 15.0 package software. p < 0.05 Values were considered statistically significant. BMI and thickness of ASAT and MAT increased with aging both in male and female individuals. There was a positive correlation between PI and weight, thickness of ASAT and thickness of MAT, while a negative correlation was found between PI and height (p < 0.01). SS angle was positively correlated with weight (p < 0.01). A weak positive correlation was found between PT angle and thickness of MAT and height (p < 0.05). The rate of transitional vertebrae and isthmic spondylolisthesis was 2 and 4.6 %, consecutively. PI and SS values were significantly higher in the subjects having spondylolisthesis than normal population (p < 0.01). It should be kept in mind that obesity might increase the risk for development of spondylolisthesis by causing increase in PI angle.
Epstein-Barr virus encephalitis: findings of MRI, MRS, diffusion and perfusion
(TURKISH J PEDIATRICS, 2011) Ozbek, Orhan; Koc, Osman; Paksoy, Yahya; Aydin, Kursad; Nayman, Alaaddin
Ozbek O, Koc O, Paksoy Y, Aydin K, Nayman A. Epstein-Barr virus encephalitis: findings of MRI, MRS, diffusion and perfusion. Turk j Pediatr 2011; 53: 680-683 Epstein-Barr virus is an infection that is known as infectious mononucleosis. Even though the central nervous system is not a primary region of involvement of this disease, neurological complications are reported rarely. In this case report, we evaluated a 15-month-old male who presented to the pediatric neurology clinic due to high fever and a neurologic attack. His serological tests and radiological examinations (magnetic resonance imaging (MRI), MR spectroscopy (MRS), diffusion-weighted imaging (DWI) and MR perfusion) were consistent with Epstein-Barr virus encephalitis, which is a very rare complication of infectious mononucleosis. Additionally, we discuss the MRI, MRS, DWI and MR perfusion findings of our case, which were different from other cases reported in the literature.

High-sensitivity C-reactive protein, lipoprotein-related phospholipase A(2), and acute ischemic stroke
(DOVE MEDICAL PRESS LTD, 2014) Kara, Hasan; Akinci, Murat; Degirmenci, Selim; Bayir, Aysegul; Ak, Ahmet; Nayman, Alaaddin; Unlu, Ali
Background: Serum biomarkers may be useful for early diagnosis of acute ischemic stroke, exclusion of other diseases that may mimic stroke, and prediction of infarct volume. We evaluated serum high-sensitivity C-reactive protein (hs-CRP) and lipoprotein-related phospholipase A(2) (Lp-PLA2) in patients who had acute ischemic stroke. Methods: In 200 patients who presented to an emergency service (acute ischemic stroke, 102 patients; control with no stroke, 98 patients), stroke patients were evaluated with the Canadian neurological scale and diffusion-weighted magnetic resonance imaging, and all patients were evaluated with the Glasgow coma scale and their serum hs-CRP level and Lp-PLA2 activity were assessed. The volume of stroke lesions was calculated from magnetic resonance images. Results: Patients who had stroke had higher mean serum hs-CRP level (stroke, 7 +/- 6 mg/dL; control, mean +/- standard deviation 1 +/- 1 mg/dL; P <= 0.001) and Lp-PLA2 activity (stroke, mean +/- standard deviation 113 +/- 86 nmol/min/mL; control, mean +/- standard deviation 103 +/- 50 nmol/min/mL; P <= 0.001) than control patients who did not have stroke. The mean hs-CRP level and Lp-PLA2 activity were higher in patients who had greater stroke severity (lower Canadian neurological scale score) and were higher in patients who had larger volume strokes. Conclusion: Higher hs-CRP level and Lp-PLA2 activity are significantly associated with more severe neurologic impairment and larger infarct size in patients who have acute ischemic stroke. These biomarkers may be useful for rapid diagnosis and prediction of ischemic tissue volume in the early stage of ischemic stroke. These findings may be important for health care facilities that have limited access to emergency computed tomography scanning for the diagnosis of stroke.
Iliac artery ınjury during lumbar disc hernia surgery
(ELSEVIER SCIENCE INC, 2019) Şahinoğlu, Mert; Arun, Oğuzhan; Orhan, Atilla; Nayman, Alaaddin; Çalışır, Akın; Bocu, Yasin; Cebeci, Yasemin; Duman, Ateş; Yılmaz, Hüseyin; Köktekir, Ender; Karabağlı, Hakan
BACKGROUND: Vascular injury complications during lumbar discectomy are rare but potentially life-threatening. Therefore, an early diagnosis and effective treatment management is required for these complications. CASE DESCRIPTION: A 50-year-old female patient was admitted to our outpatient clinic with severe back and right leg pain. She underwent surgery for right L4-5 extruded disc herniation with general anesthesia. Sudden arterial hemorrhage occurred during discectomy performed with straight disc forceps and was controlled using hemostatic materials, with no significant decrease in blood pressure. However, the patient became hypotensive near the end of the operation. The incision was quickly closed, and she was turned to supine position. Emergency abdominal ultrasound, computed tomography, and computed tomography angiography revealed an injury of the left main iliac artery, which was repaired by endovascular stenting. Laparotomy and Bogota bag were applied because of increased intrabdominal pressure at 3 hours postoperative. In addition, a retroperitoneal catheter was placed into the area of the right retroperitoneal hematoma on the first postoperative day. Tissue plasminogen activator was administered through the catheter. On postoperative day 3, the Bogota bag was removed, and the abdomen was closed. The patient was discharged without neurodeficit on day 27. Her abdominal fascial defect was closed with a synthetic graft after 5 months. CONCLUSIONS: Although lumbar discectomy is one of the most commonly performed neurosurgical procedures, the routine rules of discectomy should not be neglected. Early detection and a multidisciplinary approach can help prevent mortality in the event of vascular injury.
Importance of imaging and recent developments in diagnosis of nonalcoholic fatty liver disease
(BAISHIDENG PUBLISHING GROUP INC, 2015) Koplay, Mustafa; Sivri, Mesut; Erdogan, Hasan; Nayman, Alaaddin
Nonalcoholic fatty liver disease (NAFLD) is one of the most common causes of chronic liver disease and is a major public health problem worldwide. It is a spectrum that includes simple steatosis, nonalcoholic steatohepatitis (NASH), fibrosis and cirrhosis. Recently, NAFLD prevalence in children and adolescents has increased too. The increasing prevalence has resulted in NASH-related chronic liver disease. Therefore, early diagnosis and treatment is quite important. Although liver biopsy is still the gold standard for diagnosis and staging of NAFLD, particularly for the diagnosis of NASH, imaging methods such as ultrasonography, computed tomography, magnetic resonance imaging with chemical shift imaging and especially magnetic resonance spectroscopy and elastography have been increasingly approved as noninvasive alternative methods. The aim of this review is to analyze the diagnostic accuracy and limitations of the imaging methods and recent developments in the diagnosis of NAFLD.

Kronik Non-Spesifik Bel Ağrılı Bireylerde Kor Stabilite, Ağrı ve Disabilite Arasındaki İlişki
(Selçuk Üniversitesi, 2023 Aralık) Güler, Mehmet Akif; Demirdel, Ertuğrul; Gezer, İlknur Albayrak; Nayman, Alaaddin; Tezcan, Ezgi Akyıldız
Amaç: Çalışmamızda, kronik non-spesifik bel ağrısı olan bireylerde lumbopelvik kor stabilite seviyesi, ağrı şiddeti ve fonksiyonel disabilite düzeyi arasındaki ilişkileri incelemeyi amaçladık. Yöntem: Bu prospektif kohort çalışması, kronik non-spesifik bel ağrılı bireyler ile gerçekleştirildi. Bireylerin ağrı şiddetini ölçmek için vizuel analog skala, fonksiyonel disabilite düzeyini belirlemek için Oswestry Özürlülük Skalası, lumbopelvik kor stabilite seviyesini değerlendirmek için Sahrmann Core Stabilite Testi uygulandı. İstatistiksel analizde, verilerin korelasyonları incelemek için Spearman’ın sıra korelasyon katsayısı kullanıldı. Anlamlılık değeri p<0,05 olarak belirlendi. Bulgular: Çalışmamız kapsamında yaşlarının ortanca değeri 35 yıl olan kronik non-spesifik bel ağrılı 36 birey değerlendirildi. Bireylerin kor stabilite seviyesi ile ağrı şiddeti arasında yüksek düzeyde negatif korelasyon olduğu belirlendi (p<0,001; r=-0,781). Fonksiyonel disabilite düzeyi ile kor stabilite seviyesi arasında orta düzeyde negatif korelasyon (p<0,001; r=-0,652); fonksiyonel disabilite düzeyi ile ağrı şiddeti arasında orta düzeyde pozitif korelasyon olduğu belirlendi (p<0,001; r=0,656). Sonuç: Çalışma sonuçlarımıza göre kronik non-spesifik bel ağrılı bireylerde lumbopelvik kor stabilitedeki azalma ağrı şiddetinin ve fonksiyonel disabilitenin artmasına yol açmaktadır. Buna göre non-spesifik bel ağrılı bireylerde lumbopelvik kor stabilitenin geliştirilmesi ile bireylerin ağrı şiddetinde ve fonksiyonel disabilite düzeyinde azalma sağlanabilir.
