Öğe Comparison of CT virtual cystoscopy of the contrast material-filled bladder with conventional cystoscopy in the diagnosis of bladder tumours(W B SAUNDERS CO LTD, 2009) Kivrak, A. S.; Kiresi, D.; Emlik, D.; Odev, K.; Kilinc, M.AIM: To investigate the value of virtual cystoscopy using contrast material to fill the bladder during routine abdominopelvic computed tomography (CT) examinations for the detection of bladder tumours. MATERIALS AND METHODS: Thirty-three consecutive patients (25 men and eight women; are range 51-82 years; mean age +/- SD, 65 +/- 7 years) who had painless macroscopic haematuria and were suspected to have bladder neoplasms were prospectively evaluated with virtual cystoscopy. After intravenous injection of contrast medium, the contrast material-filled bladders were examined with single-detector helical CT with 2-mm section thicknesses. Source CT data were transferred to a workstation for interactive navigation using surface rendering. ALL the patients also underwent conventional cystoscopy. RESULTS: The results of virtual cystoscopy were compared with the findings from the conventional cystoscopy. Seventy-one of 78 bladder tumours detected with conventional cystoscopy in 28 patients were also shown on virtual images. The bladders of five patients appeared normal on both conventional cystoscopy and virtual cystoscopy. On virtual cystoscopy, seven of the 12 lesions that were <= 5 mm in diameter could be identified. The following statistical values for the identification of bladder lesions using virtual cystoscopy were calculated: sensitivity 94%, specificity 90%, positive predictive value 87%, negative predictive value 93%, and accuracy 93%. CONCLUSION: CT virtual cystoscopy is a noninvasive technique that can be used successfully for detection of bladder tumours >5 mm in selected cases during daily routine abdominopelvic work.

Cerebral vein and sinus thrombosis (CVT) is less encountered, compared to arterial stroke. Commonly witnessed symptoms are headache, nausea, vomiting, confusion, aphasia, seizures, cranial nerve dysfunction and motor or sensorial deficits. The diagnosis is accurately determined by the help of MRI and MR venography. Multiple risk factors associated with CVT are present. Venous thrombosis tends to occur when there is an imbalance between prothrombotic and thrombolytic processes. Case report. In this report, a patient with CVT extending from left transverse and sigmoid sinuses to jugular vein and diagnosed with diabetes mellitus (DM) during this period was discussed in light of literature. The 55-year-old man was evaluated in the neurology clinic with the complaints of headache, nausea, vomiting and blurred speech. On neurologic examination, he was diagnosed with sensorial aphasia and consequently, with DM over the hospital stay. On the cranial MR venography, CVT thrombosis was detected, extending from transverse and sigmoid sinuses to internal jugular vein. Decreased level of protein C and shortage of aPTT were found. Anticoagulant treatment was carried out. All complaints were improved. Conclusion. In our subject, the existence of decreased protein C and shortage of APTT, along with DM, is a situation to increase hypercoagulability and the risk of cerebral vein and sinus thrombosis.Öğe Obstrüktif Uterovajinal Anomaliler: Us ve Bt Bulguları (Olgu Sunumu)(1997) Paksoy, Y.; Açıkgözoğlu, Saim; Yeşeri, M.; Dağdöndüren, L.; Emlik, D.; Ödev, K.Amaç: Uterovajinal anomalilerle ilgili çok çalışma olmasına rağmen bilgisayarlı tomografi (BT)ve/veya ultrasonografi (US) görüntülerini gösteren yayın azdır. Biz burada BT ve/veya US ile görüntülenen obstrüktif uterovajinal anomalili üç olguyu sunuyoruz. Olgu Sunumu: Obstrüktif uterovajinal anomalili üç olgunun BT ve/veya US bulguları özetlendi. İki olguda lezyon imperfore himen, bir olguda ise ostium vajinada kısmi obstrüksyon saptandı. BT ve/veya US, üç olguda vajinada, iki olguda uterusta, bir olguda salpinkslerde sıvı birikimini gösterdi. Sonuç: US ve BT obstrüktif uterovajinal anomalililerde değerli diagnostik ve anatomik bilgiler verir.Öğe Scurvy: Radiologic Findings [Skorbüt: Radyolojik Bulgular.](2003) Kireşi, D. A.; Emlik, D.; Ödev, Kemal[Abstract not Available]Öğe Temporomandibular Internal Derangement: Correlation of Mri Findings With Clinical Symptoms of Pain and Joint Sounds in Patients With Bruxing Behaviour(British Inst Radiology, 2003) Güler, N.; Yatmaz, P. I.; Ataoğlu, H.; Emlik, D.; Uçkan, S.Objectives: The aim of this study was to correlate magnetic resonance imaging (MRI) findings of effusion, disc displacement, condylar bony changes and disc form with clinical findings of pain and sounds in patients with bruxing and non-bruxing behaviour. Methods: Disc displacement was confirmed by MRI in 102 joints from 64 patients (total of 128 joints) with bruxing behaviour who were referred for clinically diagnosed internal derangements of the temporomandibular joint (TMJ). Sixty joints with internal derangement from 30 patients without bruxing behaviour served as a control group. The clinical inclusion criteria were pain in the preauricular area and muscles of mastication, limitation or deviation in mandibular range of motion, and TMJ sounds. Signs of bruxism were diagnosed clinically and were obtained from the patient's history given on their first visit. Pain was evaluated using a visual analogue scale. Results: Of the 102 joints in the study group with disc displacement, 53 (52%) showed disc displacement with reduction and 49 (48%) showed disc displacement without reduction. In the control group, 16 joints were classified as normal. Of the remaining 44 joints, 27 (61%) had disc displacement with reduction and 17 (39%) had unilateral disc displacement without reduction. Condylar bony changes were seen in 55% of the reducing joints in the study group and in 38% of the reducing joints in the control group, compared with 86% of the non-reducing joints in the study group and 24% of the non-reducing joints in the control group. There was a strong correlation between age and degenerative change in the study group. In the reducing joints, there was a significant difference in the prevalence of condylar bony changes between the study and control groups (P < 0.01). In non-reducing joints, 30% of painful joints in the study group and 59% of those in the control group showed a strong signal in the joint space on T-2 weighted imaging. Statistically significant differences between the study and control groups were also found for disc form and the prevalence of effusion and disc displacement. Joint sounds were important in unilaterally affected joints in the study group. A statistically significant correlation was found between joint sounds and reducing joints (P < 0.05). Conclusion: It was demonstrated that a higher prevalence of condylar bony changes occurred in reducing joints in patients with bruxing behaviour.
