The evaluation of disc and extra-disc pathologies with MDCTPurpose: The aim of this study is to evaluate the diagnostic value of MDCT for lumbar spine pathologiesin routine abdominal CT examinations. Materials and Methods: 50 cases those performed abdominal CTexamination for any complaint were taken to investigation and evaluated to determine lumbar spinepathologies . In our study, all abdominal CT examined patients were studied by lumbar MR. AbdominalCT examination was performed by MDCT with four canal. IV contrast medium was administered to allpatients that were going to examined by CT. After examination, all images were transferred to workstationand they were evaluated in sagittal, coronal and axial plans. Lumbar spine pathologies were classified infour groups as disc pathologies, axis pathologies, bone lesions and other degenerative changes. All patologieswere identified by MDCT. MR evaluations were made by same radiologist at different time. CT and MRIfindings of each patient in lumbar spine patologies had been revealed. The MDCT findings of as a goldstandart MR are accepted in lumbar spine patologies were compared with MR findings of the same patients.Thus, we evaluated the rate of accuracy of MDCT in lumbar spine patologies. Results: Posterior bulging %46.4, posterior disc herniation % 100, axis pathologies % 100, bone lesions % 66.7, narrow canal and narrownoral foramen % 66.7 and schmorl nodul % 87 were detected with MDCT accuracy. Disc calsification andvacum fenomen were only detected by CT. Discussion: We can use MDCT for the evaluation of many lumbarspine patology safely. Sagittal and coronal images are a feature of MDCT that have very important diagnosticvalue in lumbar spine pathologies. Lumbar spine pathologies should be specify at abdominal CT reports

Amaç: Bu çalýþmanýn amacý ÇDBT ile yapýlan rutin abdomen BT incelemelerinin lomber omurga patolojileriaçýsýndan tanýsal önemini deðerlendirmektir. Gereç ve Yöntem: Herhangi bir nedenle abdomen BT çekilenve bu tetkiklerde lomber omurga patolojileri açýsýndan deðerlendirme yapýlan 50 olgu çalýþmaya dahil edildi.BT incelemeyi takiben tüm hastalar lomber disk patolojilerine yönelik lomber MRG inceleme ile deðerlendirildi.Abdomen BT incelemesi 4 kanallý BT ile gerçekleþtirildi. Tüm hastalara IV kontrast madde uygulandý.Çekimden sonra tüm görüntüler iþ istasyonuna gönderilerek sagittal, koronal ve aksiyel planlarda incelendi.Lomber spinal patolojiler disk patolojileri, aksis patalojileri, kemik lezyonlarý ve diðer dejeneratif deðiþikliklerolarak dört sýnýfa ayrýldý. Tüm patalojiler ÇDBTde tanýmlandý. MRG deðerlendirmeleri farklý bir zamandaayný radyolog tarafýndan yapýldý. Her hastanýn lomber spinal patolojiler açýsýndan BT ve MRG bulgularýyorumlandý ve her iki tetkikteki bulgularý karþýlaþtýrýldý. Sonuç olarak lomber spinal patolojilerde ÇDBTnindoðruluk oranlarý deðerlendirildi. Bulgular: ÇDBTde posterior disk taþmasý (PDT) % 46.4, posterior diskherniasyonu (PDH) % 100, aksis patolojileri % 100, kemik lezyonlarý % 66.7, dar kanal ve dar nöral foramen% 66.7 ve schmorl nodülü % 87 doðruluk oranýyla saptandý. Disk kalsifikasyonu ve vakum fenomeni sadeceBT de saptandý. Sonuç: Lomber spinal patolojilerin deðerlendirilmesinde ÇDBT yi güvenle kullanabiliriz.ÇDBTnin sagittal ve koronal görüntü özellikleri lomber spinal patolojileri deðerlendirmede oldukça önemlidir.Lomber spinal patolojiler abdomen BT raporlarýnda belirtilmelidir
