为比较有心绞痛和无痛性心肌缺血病人的心肌受损范围,作者给112例经冠状动脉造影确诊的一组连续的冠心病人作了~(201)铊心肌灌注显像。检查相隔不到一个月。患者先按 Bruce 方案作平板运动试验,同时作12导联心电图。在达到运动量高峰时静脉注射3mCi~(201)铊,再继续运动1分钟。然后用SPECT(核素发射单光子断层显像)显示左室心肌灌注情况。3～5小时后再作延迟显像,观察~(201)铊再分布情况。SPECT 显示左室心尖部、中部和心底部三个平面,每个平面
To compare the extent of myocardial damage in patients with angina pectoris and painless myocardial ischemia, we performed ~ (201) thallium myocardial perfusion imaging in a series of 112 consecutive patients with coronary artery disease confirmed by coronary angiography. Check less than a month apart. Patients first according to Bruce program for treadmill exercise test, at the same time for 12-lead ECG. At the peak of exercise, intravenous injection of 3mCi ~ (201) thallium, and then continue for 1 minute. Left ventricular myocardial perfusion was then visualized using SPECT (radionuclide emission single photon tomography). Delayed imaging was performed 3 to 5 hours later to observe the thallium redistribution of ~ (201). SPECT shows the left ventricular apex, middle and bottom of the heart three planes, each plane
