101. Spondylolisthesis - which of these you would not do :
A. CT scanB. MRI
C. lumbar region x-ray- AP view
D. lumbar region x-ray - lateral view
Explanation:
I personally think the answer is C. About the other options, CT scan generally gives axial sections of the spine, by which the anterior movement of one vertebra over other is difficult to assess. However, there is 3D imaging option in CT which helps us to image the spine in all the planes (coronal,sagittal etc) by which spondylolisthesis can be detected. The MRI is always the gold standard for any spine pathologies because of its varied techniques and varied planes of visualization. The lumbar spine lateral view X-ray gives us a very clear indication of the spondylolisthesis by easily demonstrating the anterior movement of one vertebral body over other and disturbing the anterior and posterior vertebral lines.AP lumbar region x-ray is the least useful of the options given below, because it is difficult to assess spondylolisthesis, when you are looking at the spine anteroposteriorly or posteroanteriorly. So the answer is C.
