However, duplex (doppler with B-mode) ultrasound is  less sensitive than CT-angiography and MRA for detecting atherosclerotic RAS and FMD-related RAS, but convenient availability, modest expenditure, non-irradiating and easily providing information about kidney size, the hemodynamic impact of the stenosis, and associated renal disease, makes DUS as a reasonable first-line screening imaging modality.
