摘要
对患有心血管疾病或患病风险较高的人进行早期诊断对提高他们的生活质量至关重要。在心脏结构、功能及射血分数发生改变之前,心肌的整体或局部应变已经发生了变化,因此心肌应变在许多心血管疾病的诊断、风险分层和预测预后中有着重要作用。心血管磁共振(cardiovascular magnetic resonance,CMR)以其高时空分辨率和软组织分辨率成为评价心肌结构和功能的金标准。心血管磁共振心肌特征追踪(cardiovascular magneti cresonance feature tracking,CMR-FT)技术无需额外的扫描序列和复杂耗时的后处理,,拥有良好的可重复性,因此CMR-FT技术已成为研究心肌应变的热点。现就基于CM-FT的心肌应变在评估心脏功能方面的研究进展进行综述。
Early diagnosis of cardiovascular disease or high-risk individuals is crucial to improving their quality of life.Global or regional myocardial strain has already changed before changes in cardiac structure,function,and ejection fraction.Therefore,myocardial strain plays an important role in the diagnosis,risk stratification,and prognosis prediction of many cardiovascular diseases.Cardiovascular magnetic resonance(CMR) has become the gold standard for evaluating myocardial structure and function due to its high spatial and temporal resolution and soft tissue resolution.Cardiovascular magnetic resonance feature tracking(CMR-FT) technology does not require additional scan sequences and complex time-consuming post-processing and has good repeatability,Therefore,CMR-FT technology has become a hot topic in the study of myocardial strain.This review summarizes the research progress on the assessment of cardiac function based on CMR-FT myocardial st rain.
