title: Use of the Doppler flowmeter in stroke prevention.
abstract: The directional Doppler flowmeter can be used to identify collateral patterns of extracanial arterial blood flow that are associated with hemodynamically significant lesions of the internal carotid artery. The use of this non-invasive technique can identify accurately those patients who are candidates for angiographic confirmation.
