Abstract/OtherAbstract:
|
Power Doppler imaging has recently gained attention as an additional color flow imaging technique that overcomes some of the limitations of conventional color Doppler ultrasound (US). Limitations of conventional color Doppler US include angle dependence, aliasing, and difficulty in separating background noise from true flow in slow-flow states. Owing to its increased sensitivity to flow, power Doppler sonography is valuable in low-flow states and when optimal Doppler angles cannot be obtained. Longer segments of vessels and more individual vessels can be visualized with power Doppler US than with conventional color Doppler sonography. Power Doppler sonography increases diagnostic confidence when verifying or excluding testicular or ovarian torsion and confirming thrombosis or occlusion of vessels. Power Doppler sonography also improves evaluation of parenchymal flow and decreases examination times in technically challenging cases. Power Doppler US is a useful adjunct to mean-frequency color Doppler sonography, especially when color Doppler US cannot adequately obtain or display diagnostic information. |
