The authors describe their initial experience with examination of the heart by magnetic resonance (MR) and discuss its position in the diagnostic algorithm of cardiac examinations:. They made 31 MR examinations of the heart in 30 patients. Echocardiography preceded 29 examinations. MR proved to be particularly useful where echocardiography did not lead to a decisive conclusion and called for confirmation by another method, or where it could not be carried out or its result was not consistent with the patient's clinical condition or the results of other examinations. The quality of the MR image was influenced most by the possibility of ECG gating. The latter was not possible in 16 patients (51.6%). In three of these (18.8%) the images were of such poor quality that they did not provide adequate diagnostic information. Images suitable for evaluation were obtained in 28 examinations (90.3%)--in these patients the MR information was valuable for establishment of the diagnosis. Magnetic resonance is a new possible method in the non-invasive diagnosis of heart disease. In the majority of cases it follows after echocardiographic examination which remains due to its accessibility the basic non-invasive method for examination of the heart.
作者描述了他们最初使用磁共振（MR）检查心脏的经验，并讨论了其在心脏检查诊断流程中的地位。他们对30例患者进行了31次心脏MR检查。其中29次检查之前做过超声心动图检查。事实证明，在超声心动图检查未得出决定性结论且需要另一种方法进行确认时，或者在无法进行超声心动图检查、其结果与患者临床状况或其他检查结果不一致的情况下，MR检查特别有用。MR图像的质量受心电图门控可能性的影响最大。16例患者（51.6%）无法进行心电图门控。其中3例（18.8%）图像质量很差，无法提供足够的诊断信息。28次检查（90.3%）获得了适合评估的图像——在这些患者中，MR信息对确诊很有价值。磁共振是心脏病无创诊断中的一种新的可行方法。在大多数情况下，它在超声心动图检查之后进行，由于超声心动图易于操作，它仍然是心脏检查的基本无创方法。
