In this review, we aimed to describe the renal CTA technique and imaging findings of several renal arterial (i.e. atherosclerosis, fibromuscular dysplasia, aneurysms of the renal arteries, dissection, vasculitidis, follow-up of patients with renal arterial stent) and venous (i.e. nut-cracker syndrome, pelvic congestion syndrome) pathologies.
