Echocardiography is the preferred imaging modality for detecting left ventricular thrombi due to its wide availability, noninvasiveness, and low cost.
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 infonnation 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.
