Vascular Ultrasound: A Radiologist Perspective

Color Doppler flow imaging (CDFI) is an evolutionary technical development that has considerably improved the diagnostic efficacy and clinical role of vascular ultrasound. The appropriate use of CDFI rests on an understanding of the instrumentation, factors affecting image quality and artifact, as well as the pathophysiology of the central and peripheral circulation. The modality has reached a relative plateau of performance. In this review, applications of CDFI for studies of the neck, abdomen, and extremities are evaluated.
