Renal artery stenosis in hypertensive patients with or without type 2 diabetes: a comparative magnetic resonance angiography study.

Background: Increased prevalence of various vascular diseases is common in type 2 diabetes mellitus. However, the increased prevalence of renal artery atheroma resulting in renal artery stenosis in patients with diabetes mellitus has not been fully assessed. We used magnetic resonance angiography to assess the prevalence of renal artery stenosis in a group of patients with hypertension and type 2 diabetes mellitus and compared them with a group of hypertensive patients without diabetes.
