title: Extracranial vascular angiography.
abstract: Noninvasive procedures (ultrasound, CT, and MRI) are increasingly valuable in the diagnosis of diseases of the head and neck. Angiography, however, is still essential in the demonstration of vascular pathology, including the preoperative evaluation of vascular neoplasms. Through angioplasty and embolization techniques, angiography also plays a leading role in the treatment of arteriosclerotic vascular disease, vascular malformations, and vascular neoplasms.
