Gated cardiac blood pool scintigraphy is a noninvasive method to assess regional and global left ventricular function in the patient with suspected true or false left ventricular aneurysm after a myocardial infarction. The procedure is easy to perform and provides reproducible, high resolution images that can accurately distinguish from diffuse contractile abnormalities often present after myocardial infarction. An overall accuracy rate of 96 percent for detection of left ventricular aneurysm can be obtained with gated cardiac blood pool scintigraphy as compared with contrast left ventriculography. The procedure also permits assessment of functional reserve of the noninvolved myocardium and thus can provide valuable information on whether enough viable myocardium will remain after aneurysmectomy. The addition of thallium-201 myocardial perfusion scintigraphy may aid in the separation of viable from scarred myocardium at the edge of the aneurysm. Both radionuclide techniques are well suited for screening the patient after infarction with persistent congestive heart failure, malignant arrhythmia or systemic emboli in whom a left ventricular aneurysm may have developed.
门控心血池闪烁扫描术是一种无创方法，用于评估心肌梗死后疑似真性或假性左心室室壁瘤患者的局部和整体左心室功能。该检查操作简便，可提供可重复的高分辨率图像，能准确区分心肌梗死后常出现的弥漫性收缩异常。与对比剂左心室造影相比，门控心血池闪烁扫描术检测左心室室壁瘤的总体准确率可达96%。该检查还可评估未受累心肌的功能储备，从而能提供关于室壁瘤切除术后是否会保留足够存活心肌的有价值信息。添加铊-201心肌灌注闪烁扫描术可能有助于区分室壁瘤边缘存活心肌与瘢痕心肌。这两种放射性核素技术都非常适合筛查心肌梗死后出现持续性充血性心力衰竭、恶性心律失常或全身性栓塞且可能已发生左心室室壁瘤的患者。
