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 important to recognize because a number of changes occur normally throughout the healing period. ⋯ Disc space infection, although uncommon, is a critical diagnosis, but can be confused with degenerative end plate changes. Arachnoiditis and spinal stenosis also show characteristic imaging findings.

ReviewThe role of intravascular ultrasound in acute traumatic aortic rupture.
Acute traumatic aortic rupture is a lethal injury and requires immediate diagnosis and surgical repair. The standard of diagnosis for aortic rupture is aortography. In patients in whom the angiographic findings of rupture are subtle or uncertain, intravascular ultrasound (IVUS) imaging of the descending aorta has been useful in confirming or excluding mural injury. However, because IVUS is unable to provide a complete and expeditious survey of the aorta and brachiocephalic arteries, the diagnosis of rupture will continue to rely on aortography or current generation computed tomography.
