Title

"artificial intelligence for contrast-free MRI: scar assessment in myocardial infarction using deep learning-based virtual native enhancement"

“virtual native enhancement”译作“虚拟原生增强”，即GAN（Generative adversarial network，生成对抗网络）。

proof-of-principle histopathologic comparison xxx also was performed >> 组织病理学的验证同样开展了。

sum. 使用基于深度学习的虚拟原生增强方法评估心肌梗死后瘢痕。一项非增强磁共振图像的人工智能研究。

Abstract

O_心脏瘢痕评估的非侵袭性“金标准”：采用轧延迟显影方法的心血管系统磁共振成像。

“a contrast-free approach would provide many advantages, including a faster and cheaper scan without contrast-associated problems.” 简炼描述了非增强方法的优势：快、便宜、无对比剂相关的各种问题（过敏、肾功要求和影响等等）。

O_the full width at half maximum method: 半高宽法，描述凸曲线特征——半峰值时的宽度。

O_the centerline chord method: 中心线和弦法，

O_bulls-eye plots: 同心圆图。

O_scar transmularity:疤痕透壁性 。
