Computed Tomography Imaging of Cardiac Masses.

Although not considered a first-line modality for assessing cardiac masses, computed tomography (CT) can provide clinically useful information and is underused for this purpose. In addition to characterizing masses with insights about presence of fat or calcification and the perfusion characteristics of a mass, CT produces high-resolution four-dimensional images depicting the mass and its relationship to chambers, valves, and coronaries. This is combined with imaging of the chest, abdomen, or coronaries. Advances in CT technology, such as dual-energy CT, dynamic perfusion imaging, and three-dimensional printing for preoperative planning, will increase the role of CT in assessment of cardiac masses.
