为了评价的~(99m)Tc-MIBI心肌灌注显像的临床应用效果,作者检查了42例男性冠心病人:第一组22例心绞痛病人(平均58岁),作了~(99m)Tc-MIBI和~(201)Tl运动后和静息心肌灌注显像.~(99m)Tc-MIBI剂量为555MBq(15mCi),注射后1.5～2小时显像.运动和静息时的SPECT显像分别在两天进行.~(201)Tl剂量为74MBq(2mCi).第二组病人(平均56岁)有心肌梗塞史,只做静息显像,另加做~(99m)Tc标记自身红细胞作首次通过心室造影,并从该组病人的~(99m)Tc-MIBI灌注显像的冠状和矢状切面来估算左室射血分数(EF)及与心室造影的EF作比较.
To evaluate the clinical utility of ~ (99m) Tc-MIBI myocardial perfusion imaging, we examined 42 patients with coronary heart disease: 22 patients with angina pectoris (mean 58 years) in the first group and 99m Tc- MIBI and ~ (201) Tl after exercise and rest myocardial perfusion imaging. ~ (99m) Tc-MIBI dose of 555MBq (15mCi), 1.5 ~ 2 hours after injection imaging. SPECT imaging at rest and at rest (201) The Tl dose was 74 MBq (2 mCi). The second group of patients (mean age 56 years) had a history of myocardial infarction with resting imaging alone and with 99m Tc-labeled red blood cells Ventricular contrast echocardiography was performed for the first time and left ventricular ejection fraction (EF) was estimated from coronal and sagittal sections of ~ (99m) Tc-MIBI perfusion imaging in this group of patients and compared with EF of ventricular angiography.
