When using fluorescence angiography (FA) in perioperative perfusion assessment, repeated measures with re-injections of fluorescent dye (ICG) may be required. However, repeated injections may cause saturation of dye in the tissue, exceeding the limit of fluorescence intensity that the camera can detect. As the emission of fluorescence is dependent of the excitatory light intensity, reduction of this may solve the problem. The aim of the present study was to investigate the reproducibility and reliability of repeated quantitative FA during a reduction of excitatory light.
在围手术期灌注评估中使用荧光血管造影（FA）时，可能需要重复注射荧光染料（吲哚菁绿，ICG）进行多次测量。然而，重复注射可能会导致组织中染料饱和，超过相机能够检测的荧光强度极限。由于荧光发射取决于激发光强度，降低激发光强度可能会解决这个问题。本研究的目的是探讨在降低激发光强度的情况下，重复定量FA的可重复性和可靠性。
