In the AP view, indicators of a normal spine include vertical alignment of the spinous processes, smooth undulating borders created by lateral masses, and uniformity among the disc spaces. Appropriateness criteria | Low Back Pain - Radiologyinfo.org Generally, non-contrast imaging is popular with most orthopedic studies, since the imaging comes out clear without the contrast dye.

MR Imaging Findings in Cauda Equina Gnathostomiasis 1. This region is more prone to injury because of the change in orientation of the facet joints between the thoracic spine and the lumbar spine and because it lies directly beneath the more rigid thoracic spine, which is stabilized by the rib cage. The diagnosis of cauda equina syndrome generally is possible on the basis of medical history and physical examination findings. As a result of inflammation, the nerve roots become adherent to each other and to the theca. The MRI scan should clearly show whether or not the cauda equina nerves are being compressed.

Compressed cauda equina nerves can cause pain, weakness, incontinence and other symptoms. Gallium 67 had a sensitivity of 92 percent, a specificity of 100 percent, and an accuracy of 95 percent.27 MRI was the second-best method of evaluation for infection, with a sensitivity of 96 percent, a specificity of 93 percent, and an accuracy of 94 percent.27. The patient's symptoms and signs will depend on the location of the hematoma, and the degree of spinal cord/cauda equina compression. Patients commonly present to family physicians with low back pain. 2. CT without contrast may be useful if MRI is not available or contraindicated.
