Contrast mediaThirty-eight lumbar disc levels were re-explored following CT in patients with a failed back surgery syndrome. Comparison of the noncontrast CT (NCCT) and contrast-enhanced CT (CECT) with the operative findings showed that in the majority of cases, NCCT was sufficient for diagnosis...
The results of magnetic resonance (MR) imaging and computed tomography (CT) in 18 patients with known degenerative disk disease of the lumbar spine were compared. In 60 intervertebral disk levels studied, there were 17 disks with degeneration and disk bulge, and 15 herniated disks. Final diagnose...
CT of the lumbar spine—Stenosis and arthrosis 来自 Semantic Scholar 喜欢 0 阅读量: 34 作者:Helms,A Clyde 摘要: A review of spinal stenosis as studied by CT is given with am emphasis on the acquired form caused by degenerative disease. Neuroforaminal stenosis and lateral recess disease are ...
The postoperative lumbar spine: imaging considerations. MRI with intravenous contrast has recently become the imaging modality of choice in the evaluation of patients developing recurrent back pain or symptoms following laminectomy and/or discectomy. The normal postoperative appearance is imp... JJ Duda,...

Axial and parasagittal computed tomographic (CT) scans and magnetic resonance (MR) images and exactly corresponding sections obtained with the freezing microtome in 18 human cadavers were examined to characterize the radiologic appearance of the lumbar neural forminal ligaments, which have been thought ...
