CMR is increasingly being used in the evaluation of stenosis in the peripheral, carotid, and renal arteries. It has better contrast resolution compared to CT and ultrasound in the evaluation of peripheral arterial disease. CE MRA has greater than 95% sensitivity and specificity to detect stenosis with the benefit of avoiding blooming artifact secondary to atherosclerotic calcification as is seen on CTA. It is particularly useful in patients with advanced calcified atherosclerotic disease in the infrageniculate vessels [95]. By utilizing time‐of‐flight MRA, gadolinium can be avoided in patients with diminished renal function. CE MRA techniques now rival CTA and conventional angiography for the assessment of carotid stenosis and aneurysms [96–98]. CE MRA has been shown to be an excellent alternative to CTA without ionizing radiation in patients undergoing evaluation for fibromuscular dysplasia in the renal arteries [99].
