May aid noninvasive carotid stenosis screening; leaves open need for arteriographic confirmation given moderate specificity.
Do MR angiography and color Doppler sonography accurately detect internal carotid artery stenosis compared to arteriography in patients?
Two-dimensional time-of-flight MR angiography combined with color Doppler sonography is a useful approach for detecting and grading the severity of carotid artery stenoses.
Polak et al. (1992) studied this question.
