^（99m）Tc－MIBI心肌三维立体显像在心肌梗塞诊断中的应用

Application of ￣(99m)Tc-MIBI SPECT Three Dimensional Myocardial Imaging in Patients With Cardiac Infarction

对５例正常人，１８例心肌梗塞患者分别进行了ＳＰＥＣＴ心肌断层显像和三维立体显像。结果显示：三维立体显像和对正常人提供近似实际解剖标本的图像；在心肌梗塞显示病灶直观、形象。对心肌表层的梗塞病变，在解剖定位、病变范围及程度估价方面明显优于断层显像；诊断深部病变时应与断层显像结合。

In this study, 5 normal subjects and 18 cardiac infarction patients were examined with SPECT 99m Tc-MIBI myocardial tomography and three dimensional(3D)imaging. The result showed that 3D imaging has significant value in the diagnosis of cardiac infarction. 3D imaging was superior to myocardial tomography imaging in determining the location and size of superficial lesins.For the diagnosis of lesser or deep lesions,it was better to combine 3D imaging with myocardial tomography imaging
