Answer 10

10.  Choice B is the correct answer.  Renal angiography is considered the gold standard for diagnosis of renal vascular disease.  Renal vascular disease should be considered a correctable cause of secondary hypertension.  Plasma renin is only elevated 50-80 percent of the time in those with renal hypertension.  MRA of the Renal Arteries and Doppler Ultrasonography of the kidneys and renal arteries are considered less sensitive modalities for diagnosis of renal vascular disease.
