Renal artery stenosis MRA
Editor-In-Chief: C. Michael Gibson, M.S., M.D. [1]
Overview
Magnetic resonance angiography (MRA) is a first line imaging technique for the diagnosis of ARAS. It should be avoided in patients with metallic objects and stents and those with claustrophobia.
Magnetic Resonance Angiography
Diagnosis by MRA is considered class I recommendation. Gadolinium-based MRA has less nephrotoxic characterstics with good visualization of the renal arteries and perirenal pathologies. Claustrophobia or presence of previous stents or metallic objects are considered contraindications for the use of MRA.[1]
