Imaging of cardiac masses is technically highly demanding. Imaging techniques should fulfill the following requirements: excellent spatial and temporal resolution, short imaging time, broad availability, low cost. Diagnostic questions include: tumor origin, size, extension, tissue type, functional consequences of tumor involvement. Transthoracic echocardiography is the imaging technique of choice in most patients. If clinical questions remain, TEE, CT or MRI can be used as secondary imaging techniques. Advantages of MRI include: excellent spatial and temporal resolution, multiplanar capabilities, large field of view, lack of radiation. Pericardial and intracardiac as well as paracardiac masses are depicted in great detail and therapeutically relevant information is usually obtained in addition to what is known from echocardiography. Although tissue differentiation is possible, a histologic diagnosis cannot be obtained. Disadvantages of MRI are artifacts in patients with severe arrhythmias or dyspnoea.

UI	MeSH Term	Description	Entries
D008279	Magnetic Resonance Imaging	Non-invasive method of demonstrating internal anatomy based on the principle that atomic nuclei in a strong magnetic field absorb pulses of radiofrequency energy and emit them as radiowaves which can be reconstructed into computerized images. The concept includes proton spin tomographic techniques.

D009206	Myocardium	The muscle tissue of the HEART. It is composed of striated, involuntary muscle cells (MYOCYTES, CARDIAC) connected to form the contractile pump to generate blood flow.

D010496	Pericardium	A conical fibro-serous sac surrounding the HEART and the roots of the great vessels (AORTA; VENAE CAVAE; PULMONARY ARTERY). Pericardium consists of two sacs: the outer fibrous pericardium and the inner serous pericardium. The latter consists of an outer parietal layer facing the fibrous pericardium, and an inner visceral layer (epicardium) resting next to the heart, and a pericardial cavity between these two layers.

D006338	Heart Neoplasms	Tumors in any part of the heart. They include primary cardiac tumors and metastatic tumors to the heart. Their interference with normal cardiac functions can cause a wide variety of symptoms including HEART FAILURE; CARDIAC ARRHYTHMIAS; or EMBOLISM.

D012680	Sensitivity and Specificity	Binary classification measures to assess test results. Sensitivity or recall rate is the proportion of true positives. Specificity is the probability of correctly determining the absence of a condition. (From Last, Dictionary of Epidemiology, 2d ed)	Specificity,Sensitivity,Specificity and Sensitivity
