TI-201 myocardial scintigrams from 100 patients were reviewed for evidence of left ventricular aneurysms without prior knowledge of the clinical or angiographic data. Scintigraphic evidence of left ventricular aneurysms was considered present when TI-201 myocardial activity extended outward from the expected left ventricular contour in a region adjacent to an area of resting scintigraphic hypoperfusion. Scintigraphic findings suggestive of left ventricular aneurysm were detected in four patients, of whom three had angiographic evidence of left ventricular aneurysm. In the fourth patient, a dilated, akinetic left ventricular apex was present but an angiographic diagnosis of left ventricular aneurysm was not made. In three additional patients with angiographic evidence of left ventricular aneurysm, scintigraphic criteria for left ventricular aneurysm were absent. Although ungated TI-201 myocardial scintigraphy is an insensitive technique for the detection of left ventricular aneurysm, a characteristic scintigraphic pattern should suggest that a left ventricular aneurysm is present.
在对100例患者的铊-201心肌闪烁扫描图进行回顾时，事先未了解其临床或血管造影数据，以寻找左心室室壁瘤的证据。当铊-201心肌活性在与静息闪烁扫描灌注减低区域相邻的区域从预期的左心室轮廓向外延伸时，即认为存在左心室室壁瘤的闪烁扫描证据。在4例患者中检测到提示左心室室壁瘤的闪烁扫描结果，其中3例有左心室室壁瘤的血管造影证据。在第4例患者中，存在扩张、运动不能的左心室心尖，但未作出左心室室壁瘤的血管造影诊断。另外3例有左心室室壁瘤血管造影证据的患者，不存在左心室室壁瘤的闪烁扫描标准。尽管非门控铊-201心肌闪烁扫描术是检测左心室室壁瘤的一种不敏感技术，但一种特征性的闪烁扫描模式应提示存在左心室室壁瘤。
