[Comparison of the clinical usefulness of magnetic resonance (MR), computer tomography )CT) and radiculography (R) in diagnosing lumbar discopathy].
The aim of the study was an assessment of the usefulness of magnetic resonance imaging (MRI), computed tomography (CT), and radiculography (R) in the diagnosis of lumbar discopathy. The accuracy of MRI, CT, and R for the diagnosis of lumbar herniated nucleus pulposus ws compared prospectively in 120 patients, undergoing surgical exploration. MRI was the most accurate test (100%) compared with CT (95%) and R (92.5%). The false positive rate was lowest for MRI (0%), followed by CT (5%) and R (7.5%). MRI proves very favorable compared with other currently available imaging modalities for diagnosis of lumbar herniated nucleus pulposus which allows to differentiate hernia and protrusion. MRI is noninvasive, has no known side effects and no radiation exposure. It is the procedure of choice for the radio-diagnosis of lumbar disc herniations.
