Evaluation of the Cerebral Vessels

  • Robert Willinsky

Abstract

In the last decade there has been a dramatic shift to noninvasive imaging of the cerebral vessels. This is justified since selective catheter angiography (digital subtraction angiography, DSA) has a risk of neurological complications despite advances in techniques and safer contrast agents. Carotid Doppler is an excellent screening tool to study the carotid bifurcation in patients with transient ischemic attacks and stroke. Transcranial Doppler is useful to detect early vasospasm in patients with subarachnoid hemorrhage. Multi-slice computed tomography (CT) angiography (CTA) and magnetic resonance angiography (MRA) have become effective methods to image the cerebral arteries and veins. DSA is now employed selectively in treatment planning after non-invasive imaging has been used for diagnosis.
