Power Doppler Ultrasonography in Ocular and Orbital Diseases

Abstract

Purpose: The authors present a preliminary report to test the usefulness of a new technique called power Doppler ultrasonography (PD) in the study of orbital vessels. Material and Methods: The ophthalmic artery and vein as well as the central retinal artery and vein have been examined in 10 patients with a General Electric Logiq 5000 that allows the examination with both color Doppler ultrasonography (CD) and PD. Results: PD does not alias, is relatively angle independent and is able to better detect the pathways of these vessels. Conclusions: PD is a new promising technique that may be superior to CD in detecting orbital and ocular vessels.
