Abstract

To measure blood flow patterns in carotid arteries of patients with cerebrovascular diseases and healthy volunteers, we used two-dimensional phase-contrast magnetic resonance angiography (MRA). For 5 healthy volunteers and 11 patients, MRA was performed on the common, internal and external carotid arteries and the vertebral arteries at a level of 20 mm above and 20 mm below the bifurcation of the internal carotid arteries on the axial scans. The flow studies in 38 arteries of healthy volunteers all showed laminar flow, except for one common carotid artery. The flow studies of 8 arteries in patients (except one) showed turbulent flow. Stenosis was detected in all 8 arteries which exhibited conventional cerebral angiography. These results demonstrated usefulness of measuring the flow patterns in the carotid arteries of patients with cerebrovascular disease by phase-contrast MRA.
