The use of computed tomography in the assessment of cardiac masses.

Computed tomography has been found to be a useful tool in the evaluation of cardiac masses. It can be most effacious in the detection of a lesion and in the delineation of its size and location, as well as the demonstration of its relationships to intra- and extracardiac structures. It can be especially useful in areas of the heart where echocardiography can be difficult. This is particularly true for the left atrium, where lesions such as small thrombi can be missed.
