Özet
Manyetik rezonansla görüntüleme temeline dayanan manyetik rezonans kolonografi kolon patolojilerinin teşhisinde yeni diagnostik bir metoddur. Bu çalışmada amacımız kolorektal kitlelerinin tanısında manyetik rezonansla kolonografinin tanısal etkinliğini değerlendirmektir. Yöntem: Klinikte, rektal kanama, gaitada gizli kan pozitifliği veya barsak alışkanlığında değişiklik gibi nedenlerle kolon patolojisinden şüphelenilen 33 olguya (20 erkek, 13 kadın; 28-85 yaşları arasında;yaş ortalaması 78,7) manyetik rezonans kolonografi ve konvansiyonel kolonoskopi yapıldı. Tüm olgulara uygun barsak temizliği yaptırıldı. Olgular manyetik rezonans masasına supin pozisyonunda yerleştirildi. 1000-1800 mi % 0,9 NaCl içerisine 15-20 mi 0,5 mmol gadopentetate dimeglumine ilave edilerek elde edilen karışım rektal lavman yoluyla verildi. Tüm olgularda kolon distansiyonu sonrası 3B GRE manyetik rezonans kolonografi ve tamamlayıcı manyetik rezonans imajları elde edildi. Bulgular: Manyetik rezonans kolonografinin kolorektal kitlelerde sensivitesi % 90 ve spesifitesi % 100 bulundu. Sedasyon ve analjezik gerekmeksizin iyi tolere edilen manyetik rezonansla kolonografinin tanıda doğruluk oranı % 94.3'tür. Sonuç: Manyetik rezonansla kolonografi kolonun görüntülenmesinde yeni bir tekniktir. Manyetik rezonans kolonografinin multiplanar görüntüleme yapabilmesi, az invaziv olması, kolorektal kanserlerin doğru evrelendirilmesinde etkin bir rolünün olması ve günlük kullanımda uygulanabilir olması gibi avantajları vardır. Manyetik rezonans kolonografi semptomatik hastalarda kolorektal kitlelerin görüntülenmesinde ve tespit edilmesinde umut vaat eden yeni bir tekniktir.
Background/aims: Magnetic resonance colonography based on magnetic resonance imaging is a relatively new diagnostic modality for diagnosing colon pathology. The aim of this study was to evaluate its performance in detecting colorectal masses. Methods: Thirty-three patients (20 male, 13 female; age range 28-85 years; mean age 78.7) suspected of having colonic lesions because of rectal bleeding, positive fecal occult blood test results or altered bowel habits underwent magnetic resonance colonography and subsequent conventional colonoscopy. All patients underwent standard bowel preparation 24 h before magnetic resonance colonography. Patients were placed in a supine position on the magnetic resonance table. After placement of a rectal tube, the colon was filled with of a mixture of 1000-1800 ml 0.9% NaCl solution and 15-20 ml 0.5 mmol/L gadopentetate dimeglumine solution. Once colonic distension was achieved, 3D GRE magnetic resonance colonography and complementary Magnetic resonance images were taken in all cases. Results: Sensitivity of magnetic resonance colonography for colorectal masses was 90% and specificity was 100%. Percentage of correct diagnosis of magnetic resonance colonography was 94.3%. Magnetic resonance colonography was well tolerated without sedation or analgesia. Conclusions: Magnetic resonance colonography is a new technique for imaging of the colon. Magnetic resonance colonography has potential advantages of multiplanar capabilities and of being a less-invasive imaging technique; it can be implemented in daily practice and has a role in accurately staging colorectal cancers. In symptomatic patients, this new technique shows promising results for the detection and imaging of colorectal masses.
