对13例老年人作潘生丁-~(201)铊(~(201)T1)心肌灌注显像。静脉注射潘生丁(60mg/kg)后,~(201)T1显像发生三种变化:1.潘生丁对~(201)T1显像无影响——3例摄取铊正常,6例呈持续性缺损;2.药物相缺损而重分布相时缺损区再充盈,共2例;3.逆转型反应(“冠状动脉偷窃现象”),共2例。本文表明潘生丁-~(201)T1显像是一种适用于老年人的早期诊断冠心病的非侵入性方法。
Thirteen elderly patients with dipyridamole ~ (201) thallium (~ (201) T1) myocardial perfusion imaging. After intravenous injection of dipyridamole (60mg / kg), there were three changes in ~ (201) T1 imaging: 1. Dipyridamole had no effect on ~ (201) T1 imaging - normal thallium uptake in 3 patients and persistent defect in 6 patients; 2. Drug phase defect redistribution phase when the defect area refill, a total of 2 cases; 3. Reverse reaction (“coronary steal phenomenon”), a total of 2 cases. This article shows that dipyridamole ~ 201 imaging is a noninvasive method for the early diagnosis of coronary heart disease in the elderly.
