资料来源:Kim, DE 等人。 结合近红外荧光成像和显微计算机断层扫描,直接可视化脑血栓栓塞。J. Vis. Exp.(2016年)
该视频演示了近红外荧光 (NIRF) 成像,以可视化用纤维蛋白特异性探针标记的切除脑组织中的血栓。近红外光激发探头,使血栓发出荧光,从而实现大脑大动脉和小皮质血管的高对比度血栓可视化。
所有涉及动物样本的程序都经过适当的动物伦理审查委员会的审查和批准。
1. 脑组织离体近红外荧光 (NIRF) 血栓成像

图 1:脑血栓栓塞的 Ex Viv o 近红外荧光 (NIRF) 成像概述。 (A 和 B)从血栓栓塞性中风的小鼠身上取出具有代表性的脑组织。切除大脑时,采取预防措施,不要丢失大脑中动脉 (MCA) – 颈内动脉远端分叉区域(ICA,蓝色箭头)的血栓栓塞(红色箭头)。(C和D)离体近红外血栓成像。将脑组织放置在近红外成像仪(C)的不透光室内,用于在MCA-ACA分叉区域栓塞闭塞之前用花青5.5(Cy5.5)荧光标记物C15预标记的血栓(D中的红色箭头)的可视化。
