A number of imaging techniques are available for the identification of left ventricular thrombi. Echocardiography is the technique of choice because of its wide availability, noninvasiveness, and relative low cost. The accuracy of information from echocardiography depends on the skill of the technician and quality of equipment. Platelet scintigraphy, which reflects activity on the thrombus surface, plays a complementary role to echocardiography in detecting thrombi. Magnetic resonance imaging and computed tomography are potentially useful. Contrast ventriculography lacks sensitivity and specificity, and radio nuclide angiography lacks sensitivity in the diagnosis of left ventricular thrombi.
有多种成像技术可用于识别左心室血栓。超声心动图因其广泛可得、无创且成本相对较低，是首选技术。超声心动图所提供信息的准确性取决于技术人员的技能和设备质量。血小板闪烁扫描可反映血栓表面的活性，在检测血栓方面对超声心动图起到辅助作用。磁共振成像和计算机断层扫描可能有用。对比心室造影缺乏敏感性和特异性，放射性核素血管造影在左心室血栓诊断中缺乏敏感性。
