摘要:

放射性核素细胞凋亡显像具有直观、无创伤和实时在体观察细胞凋亡等特点,在脑及心肌细胞缺血再灌注损伤的观察、器官移植后排斥反应的检测、肿瘤放疗和化疗效果的评估等方面具有较好应用前景。本文主要根据临床前期的研究对放射性核素凋亡显像剂的设计、作用机制及应用进行介绍。

Abstract:

Radionuclide imaging for the cell apoptosis is a direct, noninvasive, and real-time imaging technique. It is a hopeful method for observing brain and myocardial ischemic reperfusion injury, detecting allograft rejection, and evaluating the effects of tumor chemotherapy and radiotherapy. This paper introduces the design, mechanisms, and applications of radionuclide agents based on preclinical studies.
