ABSTRACT
To assess the accuracy of MR angiography for screening vascular stenosis of the extracranial carotid arteries, 20 consecutive patients with suspected extracranial carotid atherosclerotic disease were evaluated with time-of-flight MR angiography and intra-arterial contrast angiography. Both studies were independently reviewed by three observers in a blinded manner. The internal carotid arteries were graded as either normal or mildly stenotic (0%-29%), moderately stenotic (30%-69%), severely stenotic (70%-99%) or occluded. Results of the study indicate that time-of-flight MR angiography has a high rate of agreement with contrast angiography and is an accurate screening technique of the common carotid bifurcation in patients with suspected carotid stenosis.
