摘要
本文总结３０例室壁瘤患者心肌灌注断层显像特点，并与放射性核素心室造影、Ｘ线心室造影进行了对比。结果显示，室壁瘤部位为大片放射性缺损区而不是稀疏区，且心肌形态失常，垂直长轴、水平长轴呈八字形缺损。而一般心肌梗塞为内收型缺损。室壁瘤患者心肌缺损部位为单个，不是多个。心肌缺损大小与左心室射血分数呈负相关（ｒ＝－０．６７），相关密切。心肌显像形态呈八字形与Ｘ线心室造影诊断室壁瘤比较，其诊断符合率为８６．７％，若结合核素心室造影，对室壁瘤的诊断，则更有价值。
mTc-MIBI myocardial perfusion tomography was performed in 30 patients with left ventricular (LV) aneurysm. The results of 99mTc-MIBI myocardial perfusion SPECT were compared with radionuclide ventriculography and contrast ventriculography. Our data demonstrated that a characteristic pattern of myocardial SPECT defect in 26/30 patients with LV aneurysm was found, with a concordance of 87% with contrast ventriculography. A significant negative correlation between the size of LV perfusion defect and left ventricular ejection fraction was found (r=-0.67, p<0.001). Therefore, the changes in the shape of myocardial perfusion defect combined with radionuclide ventriculography would be a very useful technique for detecting ventricular aneurysm and evaluating the prognosis.
