PY - 2017 T2 - Hurst's The Heart, 14e AB - Imaging of the vasculature has evolved greatly in the past 20 years. Although the current gold standard remains invasive x-ray angiography, noninvasive modalities such as magnetic resonance imaging (MRI) and computed tomography (CT) are becoming routine for the evaluation of patients with vascular diseases. In many instances, either MRI or CT has replaced x-ray angiography as the imaging modality of choice in the assessment of patients with suspected vascular disease, because of the ever-increasing image quality, the noninvasive application, the ease and comfort for patients, and the clinical versatility of both CT and MRI. In addition to evaluating the degree of luminal stenosis, MRI and CT can now noninvasively detect the presence and composition of atherosclerotic plaques in various arterial beds. This chapter provides a comprehensive and state-of-the-art overview of the clinical indications for MRI and CT in the evaluation of vascular diseases, focusing on both angiographic and plaque-based assessments. It also introduces emerging molecular imaging approaches for the assessment of disease activity.
