DEPIC是一种~(99m)Tc标记的异腈络合物,其体外标记过程可受水杨酸制剂的抑制,体内注射后选择性地和前清蛋白结合而存留于血池中.对4例正常自愿受试者和20例心血管疾病患者进行了血池显像评价,以探讨DEPIC作为血池显像剂其EF(射血分数)值测定结果与标记RBC法之间的可比性和有效
DEPIC is a ~ (99m) Tc-labeled isonitrile complex whose in vitro labeling process can be inhibited by salicylic acid preparations and is selectively retained in the blood pool after in vivo injection by binding to pre-albumin. Normal volunteers and 20 patients with cardiovascular disease were evaluated on blood pool imaging to explore the comparability between EF (ejection fraction) value and labeled RBC method of DEPIC as blood pool imaging agent and effective
