NOCHE, Julián  y  ALBORNOZ, Francisco. Multi-modality imaging for diagnosis and characterization of cardiac masses. Rev Chil Cardiol [online]. 2016, vol.35, n.1, pp.11-18. ISSN 0718-8560.  http://dx.doi.org/10.4067/S0718-85602016000100001.

Background: We analyzed a series of patients with cardiac masses who were studied using multiple imaging modalities, including echocardiography (ECHO), CT Scan, Magnetic Resonance imaging (RNM) and PET/CT Aim: to determine the usefulness of multi-modality imaging in determining the etiology and location of cardiac masses initially detected by ECHO Methods: 37 patients selected by the presence of a cardiac mass detected by ECHO were submitted to different modalities of cardiac imaging in order to determine the nature, location and etiology of the mass Results: 14 (39%) masses were tumors confirmed by biopsy; 11 (30%) fulfilled criteria to diagnose a thrombus; 1 patient (2.8%) had an infectious cardiac mass, another calcification of the mitral an-nulus, another turned out to be a normal variant and only in one patient (2.8%) a diagnosis was not possible. Six patients had extra cardiac masses. ECHO plus RNM were sufficient to characterize location and histologic type in 28 patients (76%). Seven cases (19%) required ECHO plus CT scan. ECHO plus CT scan plus RNM plus PET/CT was required in 1 patient to establish mitotic activity. ECHO plus RNM plus PT/CT was necessary to determine location, histologic type, presence of calcium and infectious activity Conclusion: Multimodality imaging allowed to determine etiology and location of cardiac masses in 97 % of cases. ECHO plus NMR was the combination most frequently used. CT scan was particularly useful to identify calcification and fat deposits and PET/CT to identify increased metabolic activity, either infection or mitotic activity.
