(201)TI myocardial scintigraphy was performed on 25 cases of prior myocardial infarction, and based upon phantom experiments, the infarct size was quantitatively analyzed as a defect segment percentage (DS%). DS% was compared to the left cardiac function obtained from myocardial scintigrams, RI angiocardiograms, and chest X-ray films, and the results were examined. There was a high degree of correlation between DS% and LVEF and LVEDV/ m(2) (R=-0.72, 0.84). Where DS% was less than 25%, the left ventricular function was almost normal, and where DS% was greater than 25%, deterioration could clearly be seen. There was a correlation between left ventricular volume from myocardial scintigrams and heart volume from chest X-ray films. The (201)TI uptake in the lung field from myocardial scintigrams increased as the infarct size increased, and the uptake in the upper lungs also increased.
对25例陈旧性心肌梗死患者进行了（201）铊心肌闪烁显像，并根据体模实验，将梗死面积定量分析为缺损节段百分比（DS%）。将DS%与心肌闪烁显像、放射性核素心血管造影及胸部X线片所获得的左心功能进行比较，并对结果进行了检验。DS%与左室射血分数（LVEF）及左室舒张末期容积/体表面积（LVEDV/m²）之间存在高度相关性（R = -0.72，0.84）。当DS%小于25%时，左室功能基本正常；当DS%大于25%时，则可见明显恶化。心肌闪烁显像测得的左室容积与胸部X线片测得的心脏容积之间存在相关性。随着梗死面积的增加，心肌闪烁显像肺野的（201）铊摄取增加，上肺的摄取也增加。
