This educational presentation reviews the methodological imaging and interpreting process that constitute the cardiovascular magnetic resonance (CMR) assessment of possible intracardiac mass. We present a text and pictorial summary of various intracardiac masses to demonstrate the heterogeneity commonly seen in tissue characterization, using T1, T2, fat-suppression, fat-water separation, perfusion, and late gadolinium enhancement techniques. While some masses have typical tissue characteristic presentations, the physician needs to be judicious in interpreting the CMR. CMR can identify normal structures that may appear as a pseudo-mass on other imaging modalities, and CMR can differentiate between cysts, vascular structures, fat, thrombi, and solid tumors.
