摘　　要：采用^(99m)Tc-MIBI 对心肌进行单光子发射性计算机断层显象,观察72例。其中:冠心组18例;可疑冠心组22例;单纯高血压组16例;对照组16例。受检者进行运动显象和静态显象,然后进行图象重建比较。结果:(1)对照组全部正常;(2)冠心组全部异常,其中心肌梗塞者图象显示缺血区为完全缺损;心绞痛为明显稀疏和完全缺损。完全缺损者临床及体表心电图均无心肌梗塞表现;(3)可疑冠心组16/22异常;(4)单纯高血压组8/16有可逆性稀疏或轻度稀疏。缺血区域以前壁常见。本法较静息心电图,运动心电图及二维超声心动图敏感。Rest and stress ^(99m)Tc-MIBI myocardial perfusion tomography by SPECT was performed in seven- ty two patients.Eighteen patients with coronary artery disesse(CAD),22 with suspectable coronary artery disease,16 only with primary hypertension and 16 without heary disease for control.The results were:(1)All normal in the control group.(2)All abnormal in CAD group,ischemia area of myocardial infarction showing complete filling defect imaging,ischemia area in angina patients showing markedly deficient perfusion or complete defect imaging,which may show normal in clinical findings and electro- cardiogram.(3)Sixteen abnormal in 22 patients in suspectable CAD group.(4)Eight abmormal in 16 patients of primary hypertension and only showeng slight or reversible difficient perfusion.Ischemia area was usually in the anterior wall.It is concluded that ^(99m)Tc-MIBI is more sensitive than resting, stress electrocardiography and dimensional echocardiographic examination.
