Abstract：
Cardiovascular magnetic resonance (CMR) imaging is often considered the reference method to assess cardiac tumors. However, little data exists concerning the effectiveness of CMR for the accurate diagnosis of cardiac masses. We sought to understand the diagnostic value of CMR for evaluation of suspected cardiac mass. A total of 249 consecutive CMR cases performed at a single center from January 2005 to June 2013 for evaluation of masses found on echocardiography or computed tomography (CT) were included. All the clinical data and imaging features of these patients were retrospectively reviewed and medical records were verified for follow up care. More than half of the patients referred for evaluation of masses found at echocardiography or CT were found to have no evidence of mass by CMR. CMR correctly differentiated between thrombus and myxoma in 88.4 % cases. Malignant masses were accurately diagnosed on CMR. However, CMR missed or misdiagnosed a few cases of benign masses. Diagnosing cardiac masses remains an important use for imaging, despite technical difficulties with current imaging modalities. CMR can play a key role in confirming presence or absence of a mass. Additionally, in the presence of a mass, CMR can provide accurate differentiation of pseudomasses, benign and malignant masses. However, the limitations of CMR must be recognized.
