Abstract

Power Doppler ultrasound (US) is a new technology that is superior toconventional color Doppler imaging in the detection of blood flow. Because of its greater sensitivity to flow and reduced angle: dependence, power Doppler US demonstrates optimal color filling of renal pedicular vessels and allows improved evaluation of the renal parenchymal microvasculature, Power Doppler US was used as an adjunct to conventionalcolor Doppler imaging in technically challenging cases and to improveevaluation of renal vascular disorders in a series of 916 patients, The primary clinical advantages of using power Doppler US compared withconventional color Doppler imaging include better morphologic appreciation of atherosclerotic changes in the renal artery wall, allowing improved diagnostic performance especially in hemodynamically nonsignificant plaques; ability to differentiate between subocclusive renal artery stenosis and occlusion; increased confidence in the diagnosis of renal vein thrombosis and in the assessment of caval tumor thrombus; andbetter appreciation of renal cortical perfusion defects, In addition,because of its greater sensitivity to perivascular artifact, power Doppler US has the potential to increase the detection rate for intrarenal arteriovenous fistulas.
