N2  - Summary: To determine the accuracy of computed tomography (CT scan) in the diagnosis of lumbar spine pathology in terms of foraminal stenosis, disc herniation, moderate to severe central canal stenosis, fracture and spondylolisthesis or retrolisthesis. Retrospective review of all consecutive records of patients who had abdominal CT scan reports within 1 year of lumbar MRI from January 1, 2012 to December 31, 2017 at the Diagnostic Imaging Center (DIC) of FEU-NRMF Medical Center were obtained. Plain abdominal CT studies were reviewed without any knowledge of the patients' prior lumbar spine MR findings. The lumbar spine MRI reports were used as the standard of reference. Thus, both imaging studies were correlated to determine if the lumbar spine abnormalities, in terms of foraminal stenosis, disc herniation, moderate to central canal stenosis, fracture and spondylolisthesis or retrolisthesis were diagnosed using CT scan. Data were analyzed from 165 patients wherein 315 total abnormal findings were seen on the lumbar spine MRI studies while 299 were appreciated in the CT Scan. The accuracy of abdominal CT in lumbar spine evaluation, in terms of foraminal stenosis, disc herniation, moderate to central canal stenosis, fracture and spondylolisthesis or retrolisthesis were 86.06%, 89.09%, 98.18% and 97.58% respectively. Overall accuracy was noted to be 92%. Results revealed that with recent advances in diagnostic imaging technology particularly in CT Scan, evaluation of the lumbar spine on abdominal CT studies is feasible, hence it may provide significant findings particularly to those patients who are contraindicated as well as to those in remote rural areas wherein there is lack of availability and accessibility of diagnostic MRI imaging. Though, CT scan may help in assessing the lumbar spine, it is still important to note that lumbar MRI study is still the modality of choice for a more definite analysis
