The evaluation of disc and extra-disc pathologies with MDCT

15566

Purpose: The aim of this study is to evaluate the diagnostic value of MDCT for lumbar spine pathologies in routine abdominal CT examinations. Materials and Methods: 50 cases those performed abdominal CT examination for any complaint were taken to investigation and evaluated to determine lumbar spine pathologies . In our study, all abdominal CT examined patients were studied by lumbar MR. Abdominal CT examination was performed by MDCT with four canal. IV contrast medium was administered to all patients that were going to examined by CT. After examination, all images were transferred to workstation and they were evaluated in sagittal, coronal and axial plans. Lumbar spine pathologies were classified in four groups as disc pathologies, axis pathologies, bone lesions and other degenerative changes. All patologies were identified by MDCT. MR evaluations were made by same radiologist at different time. CT and MRI findings of each patient in lumbar spine patologies had been revealed. The MDCT findings of as a gold standart 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 narrow noral foramen % 66.7 and schmorl nodul % 87 were detected with MDCT accuracy. Disc calsification and vacum fenomen were only detected by CT. Discussion: We can use MDCT for the evaluation of many lumbar spine patology safely. Sagittal and coronal images are a feature of MDCT that have very important diagnostic value in lumbar spine pathologies. Lumbar spine pathologies should be specify at abdominal CT reports.
