对３０例急性心肌梗塞患者进行心肌灌注断层显像的定位和定量分析，并与ＥＣＧ的定位和定量分析进行对比．对靶心图存在的缩小和扩大病灶因素用左室模型进行校正后．靶心图所测梗塞面积百分比与ＱＲＳ记分法所测梗塞面积百分比相关良好（ｒ＝０．７０６，Ｐ＜０．０１），心肌灌注断层显像在前壁、前间壁、前侧壁和下壁心肌梗塞的定位上与心电图相比无明显差异，在后侧壁、后间壁、后壁和心尖部梗塞的定位上明显优于ＥＣＧ（Ｐ＜０．０１）．
Myocardial perfusion tomography was performed in 30 patients with acute myocardial infarction. The results were compared with the results of ECG localization and quantification. Reducing the size of the bull’s eye map and expanding the lesion factors were corrected with the left ventricular model. The percentage of infarct size measured by bull’s-eye mapping was well correlated with the percentage of infarct size measured by QRS scoring (r = 0.706, P <0.01). Myocardial perfusion imaging was performed on the anterior wall, anterior wall, anterior wall and inferior wall There was no significant difference in the location of myocardial infarction between ECG and ECG, and the location of posterior wall, posterior wall, posterior wall and apical infarction were better than ECG (P <0.01).
