With its superb contrast resolution, multiplanar imaging capability, and large field of view, magnetic resonance imaging is the gold standard in the imaging evaluation of cardiac and juxtacardiac masses. Spin echo images graphically display the pathoanatomy of intracavitary, valvular, myocardial, pericardial, and juxtacardial masses. Dynamic imaging techniques are used to identify their pathophysiologic consequences on myocardial contraction dynamics, valvular function, or blood flow mechanics. Echocardiography is a good modality to evaluate the heart and in most institutions, remains the initial test in the workup of cardiac masses. However, equivocal echocardiographic studies are common and, in fact, are the leading indication for the use of MR in the workup of cardiac/juxtacardiac masses.
凭借其卓越的对比分辨率、多平面成像能力和大视野，磁共振成像在心脏和心脏旁肿块的成像评估中是金标准。自旋回波图像以图形方式显示腔内、瓣膜、心肌、心包和心脏旁肿块的病理解剖结构。动态成像技术用于确定它们对心肌收缩动力学、瓣膜功能或血流动力学的病理生理影响。超声心动图是评估心脏的良好方式，在大多数机构中，它仍然是心脏肿块检查的初始检查方法。然而，超声心动图检查结果不明确的情况很常见，实际上，这是在心脏/心脏旁肿块检查中使用磁共振成像的主要指征。
