Overview
CT angiography (CTA) is considered a first line imaging technique for the diagnosis of ARAS. It should be avoided in patients with renal impairment due to possible contrast-induced nephropathy following the procedure.
Computed Tomographic Angiography
Diagnosis by CT angiography is considered class I recommendation. It provides higher spacial resolution compared to MRA. CT angiography may be used in patients with normal renal function to avoid contrast-induced nephropathy in patients with impaired renal function. Presence of previous stents or metallic objects are considered a contraindication for the use of CTA.[1]
