Nineteen patients suspected of having intracavitary masses were examined by echo-cardiography and computer tomography. One 1 cm. thrombus on the mitral valve could be demonstrated only on the echo-cardiogram and was interpreted as a tumour. Both CT and echo-cardiograms produced occasional false negative findings with cardiac thrombi, which were ultimately diagnosed by the other method or by ventriculography. Differentiation between a thrombus and a tumour depends essentially on its localisation and on the history, and some morphological criteria. Echo-cardiography and densitometric measurements did not assist in the differential diagnosis. CT may be able to differentiate thrombus from tumour if the latter contained fat or has become cystic.
19名疑似有腔内肿块的患者接受了超声心动图和计算机断层扫描检查。二尖瓣上一个1厘米的血栓仅在超声心动图上显示，并被误诊为肿瘤。CT和超声心动图对心脏血栓偶尔会出现假阴性结果，最终通过另一种方法或心室造影确诊。血栓和肿瘤的鉴别主要取决于其位置、病史以及一些形态学标准。超声心动图和密度测量无助于鉴别诊断。如果肿瘤含有脂肪或已变成囊肿，CT可能能够区分血栓和肿瘤。
