延迟增强心脏磁共振（DE-CMR）成像越来越多地用于识别和量化局灶性心肌疤痕。我们的目标是描述用于解释 DE-CMR 图像的因素，并强调模仿心肌疤痕的潜在陷阱和伪影。反转恢复梯度回忆回波序列被普遍接受为 DE-CMR 的参考标准。还有一些替代序列可以在一次屏气或自由呼吸的情况下执行。放射科医生需要了解影响图像质量的因素，以及可能产生模仿心肌疤痕的局灶性高信号区域的潜在陷阱和伪影。
Delayed enhancement cardiac magnetic resonance (DE-CMR) imaging is used increasingly to identify and quantify focal myocardial scar. Our objective is to describe factors used in the interpretation of DE-CMR images and to highlight potential pitfalls and artefacts that mimic myocardial scar. Inversion recovery gradient recalled echo sequence is commonly accepted as the standard of reference for DE-CMR. There are also alternative sequences that can be performed in a single breath-hold or with free breathing. Radiologists need to be aware of factors affecting image quality, and potential pitfalls and artefacts that may generate focal hyperintense areas that mimic myocardial scar.
