简介：
Overview
This protocol describes a novel imaging technique that combines near-infrared fluorescent (NIRF) imaging and micro-computed tomography (microCT) to visualize cerebral thromboemboli. This method enables the quantification of thrombus burden and its evolution in both excised brain tissue and living animals.
