Renal Arterial Stenosis: Prospective Comparison of Color Doppler US and Breath-hold, Three-dimensional, Dynamic, Gadolinium-enhanced MR Angiography

Abstract

Breath-hold, gadolinium-enhanced MR angiography is superior to color Doppler US in accessory renal artery detection. Although the specificity of MR angiography is similar to that of color Doppler US, MR angiography has a better sensitivity and negative predictive value in depicting renal arterial stenoses.
