Power doppler ultrasonography in ocular and orbital diseases.
ABSTRACT 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.
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.
PD does not alias, is relatively angle independent and is able to better detect the pathways of these vessels.
PD is a new promising technique that may be superior to CD in detecting orbital and ocular vessels.
