Overview

Diagnosis by magnetic resonance angiography (MRA) is considered class I recommendation. Gadolinium-based MRA has less nephrotoxic characterstics with good visualization of the renal arteries and perirenal pathologies. Presence of previous stents or metallic objects are considered a contraindication for the use of MRA.[1]

CMR may be used for evaluating renal arterial stenoses and quantifying renal arterial blood flow. CE-MRA indicates contrast-enhanced magnetic resonance angiography; CMR, cardiovascular magnetic resonance; ECG, electrocardiogram; LGE, late gadolinium enhancement; LV, left ventricular; RV, right ventricular; MRA, magnetic resonance angiography; and PAD, peripheral arterial
