最近，许多研究已经证明了分段反转恢复快速梯度回波（seg IR-FGE）序列用于区分损伤心肌和正常心肌的有效性。这种延迟增强成像技术已被证明在识别心肌梗死的存在和程度以及预测冠状动脉血运重建后收缩功能的改善方面是有效的。在这篇文章中，我们概述了在我们中心进行的延迟增强成像的过程，更详细地描述了seg IR-FGE序列，包括我们选择序列设置的过程，回顾了我们的图像解释过程，并强调了我们在1500多名患者中进行该技术的经验中遇到的潜在陷阱（以及克服这些陷阱的技术）。
Recently, numerous studies have demonstrated the effectiveness of a segmented inversion recovery fast gradient echo (seg IR-FGE) sequence for differentiating injured from normal myocardium. This technique for delayed enhancement imaging has been shown to be effective in identifying the presence and extent of myocardial infarction, as well as predicting improvement in contractile function after coronary revascularization. In this article we outline the procedure of delayed enhancement imaging performed at our center, describe the seg IR-FGE sequence in more detail, including our process for choosing sequence settings, review our process of image interpretation, and highlight potential pitfalls (and techniques to overcome them) that we have encountered in our experience with performing the technique in over 1500 patients.
