MRI is rapidly becoming the imaging modality of choice in the diagnostic assessment of patients with persistent or recurrent symptoms following spinal surgery. It displays the normal postoperative findings as well as most causes of FBSS. ⋯ This can be particularly helpful in evaluating the patient with multiple lumbar surgeries. MRI can also determine the presence of other causes of the FBSS such as lateral spinal stenosis, arachnoiditis, fat graft compression on the thecal sac, and presence of postoperative hematoma or postoperative infection.

MRI is a useful diagnostic tool in the assessment of traumatic lesions of the foot and ankle. It is especially useful in demonstrating acute and chronic tendon and ligament injuries. ⋯ A bone scan may also be used to detect these fractures; however, with MRI the fracture extent may be determined. MRI is also useful in diagnosing complication of trauma, such as ischemic necrosis and bone and soft-tissue infections.
