Comparative Study
Disc space-targeted angled axial MR images of the lumbar spine: a potential source of diagnostic error.
To compare the sensitivities of contiguous axial (CA) images and disc space-targeted angled axial (DSTAA) images of the lumbar spine for: (1) the detection of spondylolysis defects, and (2) the identification of disc material which has migrated away from the parent disc. ⋯ MR imaging of the lumbar spine using contiguous axial data obtained through both the level of the disc and vertebral body demonstrates migrated disc material and spondylolysis defects better than did disc space-targeted angled data.
