Answer

CT scanning of the lumbar spine provides superior anatomic imaging of the osseous structures of the spine and good resolution for cases of disc herniation. However, the sensitivity of a CT scan without myelography for detecting disc herniation is inferior to that of MRI. As with MRI, there can be a significant number of positive findings in the asymptomatic population when CT scanning is used.
