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.
目的
作者发表一份初步报告，以测试一种名为能量多普勒超声检查（PD）的新技术在眼眶血管研究中的实用性。
材料与方法
使用通用电气Logiq 5000对10例患者的眼动脉和静脉以及视网膜中央动脉和静脉进行了检查，该设备可同时进行彩色多普勒超声检查（CD）和PD检查。
结果
PD不产生混叠，相对角度依赖性较小，并且能够更好地检测这些血管的走行。
结论
PD是一种有前景的新技术，在检测眼眶和眼部血管方面可能优于CD。
