Magnetic resonance imaging (MRI) with ECG-gated acquisition displays the blood pool as a signal void and thereby provides high contrast differentiation between cardiovascular structures and soft-tissue masses. The role of MRI for the detection and definition of the extent of paracardiac and intracardiac masses is reviewed. The extension of mediastinal, lung, and upper abdominal tumors to the heart and pericardium is depicted favorably by MRI and this attribute is also demonstrated. It is anticipated that MRI will have an increasing role in the evaluation of primary and secondary masses of the heart and pericardium.
采用心电图门控采集的磁共振成像（MRI）将血池显示为信号缺失，从而在心血管结构与软组织肿块之间提供高对比度的区分。本文综述了MRI在检测和界定心旁及心内肿块范围方面的作用。MRI能够很好地显示纵隔、肺部及上腹部肿瘤向心脏和心包的延伸情况，这一特性也得到了证实。预计MRI在评估心脏和心包的原发性及继发性肿块方面将发挥越来越重要的作用。
