Abstract

Purpose: 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.

Özet

Amaç: Bu çaly?manyn amacy ÇDBT ile yapylan rutin abdomen BT incelemelerinin lomber omurga patolojileriaçysyndan tanysal önemini de?erlendirmektir. Gereç ve Yöntem: Herhangi bir nedenle abdomen BT çekilenve bu tetkiklerde lomber omurga patolojileri açysyndan de?erlendirme yapylan 50 olgu çaly?maya dahil edildi.BT incelemeyi takiben tüm hastalar lomber disk patolojilerine yönelik lomber MRG inceleme ile de?erlendirildi.Abdomen BT incelemesi 4 kanally BT ile gerçekle?tirildi. Tüm hastalara IV kontrast madde uygulandy.Çekimden sonra tüm görüntüler i? istasyonuna gönderilerek sagittal, koronal ve aksiyel planlarda incelendi.Lomber spinal patolojiler disk patolojileri, aksis patalojileri, kemik lezyonlary ve di?er dejeneratif de?i?ikliklerolarak dört synyfa ayryldy. Tüm patalojiler ÇDBTde tanymlandy. MRG de?erlendirmeleri farkly bir zamandaayny radyolog tarafyndan yapyldy. Her hastanyn lomber spinal patolojiler açysyndan BT ve MRG bulgularyyorumlandy ve her iki tetkikteki bulgulary kar?yla?tyryldy. Sonuç olarak lomber spinal patolojilerde ÇDBTnindo?ruluk oranlary de?erlendirildi. Bulgular: ÇDBTde posterior disk ta?masy (PDT) % 46.4, posterior diskherniasyonu (PDH) % 100, aksis patolojileri % 100, kemik lezyonlary % 66.7, dar kanal ve dar nöral foramen% 66.7 ve schmorl nodülü % 87 do?ruluk oranyyla saptandy. Disk kalsifikasyonu ve vakum fenomeni sadeceBT de saptandy. Sonuç: Lomber spinal patolojilerin de?erlendirilmesinde ÇDBT yi güvenle kullanabiliriz.ÇDBTnin sagittal ve koronal görüntü özellikleri lomber spinal patolojileri de?erlendirmede oldukça önemlidir.Lomber spinal patolojiler abdomen BT raporlarynda belirtilmelidir.
