眼光学相干断层扫描血管造影:OCT血管造影
Optical coherence tomography (OCT) angiography is an important new imaging modality that is already being used by ophthalmologists in retina centers worldwide. It uses motion as intrinsic contrast, thus obviating the need to inject any intravenous dye. It uses infrared light that is invisible to the patient, and only requires few seconds per scan. This makes it both easier to use and much better tolerated by patients than traditional dye-based fluorescein angiography (FA) and indocyanine green (ICG) angiography.
光学相干断层扫描(OCT)angiography 是一种重要的新成像技术,已经在世界各地的眼科中心被眼科医生使用。它利用运动作为内在对比度,从而消除了需要静脉注射任何造影剂的需求。它使用的是不可见于患者的红外光,并且每次扫描只需要几秒钟。这使得其在使用上既比传统的基于造影剂的荧光素angiography(FA)和吲哚菁绿(ICG)angiography 更加容易,同时也被患者更广泛地接受。
