Patients imaged with 99mTc pyrophosphate for myocardial infarction between October 1975 and March 1976 were reviewed. There were 103 patients and 114 images obtained. The clinical criteria of either or electrocardiographic changes were used to validate a myocardial infarct. We experienced 92.4% true negatives, 68.7% true positives, 7.5% false positives and 31.3% false negatives. It technically compromised scans were exclude (those with blood-pool activity, overlying costal cartilage), the false-negative rate was 15.4%. These data show that the presence of a negative phosphate scan does not rule out the possibility of a recent small, less than 2.5-cm subendocardial myocardial infarction.
对1975年10月至1976年3月间使用99mTc焦磷酸盐进行心肌梗死成像的患者进行了回顾。共有103例患者,获取了114张图像。采用临床标准或心电图改变来验证心肌梗死。我们观察到真阴性率为92.4%,真阳性率为68.7%,假阳性率为7.5%,假阴性率为31.3%。若排除技术上存在问题的扫描(即存在血池活性、覆盖肋软骨的扫描),假阴性率为15.4%。这些数据表明,磷酸盐扫描结果为阴性并不能排除近期发生小于2.5厘米的心内膜下小面积心肌梗死的可能性。
