摘　　要：心力衰竭(HF)是常见心血管疾病之一,心脏磁共振(CMR)以高分辨率和无辐射等优势成为HF诊断的理想手段。快速应变编码(fast-SENC)技术是一种用于区域心肌功能测量的CMR技术,能快速准确评估心肌应变,通过生成不同颜色的编码可直接显示心肌在收缩和舒张过程中的变形情况;此外,该技术还能敏感地识别不同临床阶段HF病人的心功能异常,并为其诊断和预后评估提供可靠的影像学依据。就fast-SENC技术在HF中的应用进展予以综述。Heart failure(HF)is one of the most common cardiovascular diseases.Cardiac magnetic resonance(CMR),with its high resolution and radiation-free imaging advantages,has become an ideal imaging modality for HF diagnosis.Fast strain-encoded(fast-SENC)imaging is a CMR technique designed for assessing regional myocardial function.It not only provides rapid and accurate evaluation of myocardial strain but also visualizes myocardial deformation during contraction and relaxation through color-coded mapping.Additionally,fast-SENC technology can sensitively detect cardiac dysfunction in HF patients at various clinical stages,providing reliable imaging evidence for diagnosis and prognostic assessment.This review summarizes recent advancements in the application of fast-SENC technology in HF.
