MR EVALUATION OF CARDIAC JUXTACARDIAC MASSES

With its superb contrast resolution, multiplanar imaging capability, a nd large field of view, magnetic resonance imaging is the gold standar d in the imaging evaluation of cardiac and juxtacardiac masses. Spin e cho images graphically display the pathoanatomy of intracavitary, valv ular, myocardial, pericardial, and juxtacardial masses. Dynamic imagin g techniques are used to identify their pathophysiologic consequences on myocardial contraction dynamics, valvular function, or blood flow m echanics. Echocardiography is a good modality to evaluate the heart an d in most institutions, remains the initial test in the workup of card iac masses. However, equivocal echocardiographic studies are common an d, in fact, are the leading indication for the use of MR in the workup of cardiac/juxtacardiac masses.
