This chapter, found in the headache section of the book, provides a succinct synopsis of a key study examining the use of duplex ultrasound (DUS), magnetic resonance angiography (MRA), and digital subtraction angiography for diagnosing carotid artery stenosis. This summary outlines the study methodology and design, major results, limitations and criticisms, related studies and additional information, and clinical implications. The study showed that both DUS and MRA are very accurate for detecting carotid artery occlusion; however, MRA is more accurate than DUS in diagnosing 70%–99% carotid artery stenosis. In addition to outlining the most salient features of the study, a clinical vignette and imaging example are included in order to provide relevant clinical context.
