The objective of this review article is to discuss how cardiovascular magnetic resonance (CMR) imaging measures left ventricular (LV) function, characterizes tissue, and identifies myocardial fibrosis in patients receiving anthracycline-based chemotherapy (Anth-bC). Specifically, CMR can measure LV ejection fraction (EF), volumes at end-diastole (LVEDV), and end-systole (LVESV), LV strain, and LV mass. Tissue characterization is accomplished through T1/T2-mapping, late gadolinium enhancement (LGE), and CMR perfusion imaging. Despite CMR's accuracy and efficiency in collecting data about the myocardium, there are challenges that persist while monitoring a cardio-oncology patient undergoing Anth-bC, such as the presence of other cardiovascular risk factors and utility controversies. Furthermore, CMR can be a useful adjunct during cardiopulmonary exercise testing to pinpoint cardiovascular mediated exercise limitations, as well as to assess myocardial microcirculatory damage in patients undergoing Anth-bC.
这篇综述文章的目的是讨论心血管磁共振成像(CMR)如何测量接受蒽环类药物化疗(Anth-bC)患者的左心室(LV)功能、对组织进行特征描述以及识别心肌纤维化。具体而言,CMR可以测量左心室射血分数(EF)、舒张末期容积(LVEDV)、收缩末期容积(LVESV)、左心室应变和左心室质量。组织特征描述通过T1/T2映射、延迟钆增强(LGE)和CMR灌注成像来完成。尽管CMR在收集有关心肌的数据方面具有准确性和高效性,但在监测接受Anth-bC的心脏肿瘤患者时仍存在挑战,例如存在其他心血管危险因素和效用争议。此外,CMR在心肺运动测试期间可能是一种有用的辅助手段,以确定心血管介导的运动限制,以及评估接受Anth-bC患者的心肌微循环损伤。
