This consensus paper provides a framework for grading of severity of cardiovascular magnetic resonance (CMR) imaging-based assessment of chamber size, function, and aortic measurements. This does not currently exist for CMR measures. Differences exist in the normal reference values between echocardiography and CMR along with differences in methods used to derive these. We feel that this document will significantly complement the current literature and provide a practical guide for clinicians in daily reporting and interpretation of CMR scans. This manuscript aims to complement a recent comprehensive review of CMR normal value publications to recommend cut-off values required for severity grading. Standardization of severity grading for clinically useful CMR parameters is encouraged to lead to clearer and easier communication with referring clinicians and may contribute to better patient care. To this end, the European Association of Cardiovascular Imaging (EACVI) has formed this expert panel that has critically reviewed the literature and has come to a consensus on approaches to severity grading for commonly quantified CMR parameters.

欧洲心血管影像协会专家共识文件：对成年人心腔大小和主动脉根的心血管磁共振正常值进行全面审查，并提出分级严重性的建议。

这份共识性文件为基于心血管磁共振（CMR）影像的​​腔室大小，功能和主动脉测量评估的严重性分级提供了框架。CMR措施当前不存在此功能。超声心动图和CMR之间的正常参考值存在差异，并且用于得出这些值的方法也存在差异。我们认为该文档将极大地补充当前文献，并为临床医生在CMR扫描的每日报告和解释中提供实用指南。该手稿旨在补充最近对CMR正常值出版物的全面综述，以推荐严重度分级所需的临界值。鼓励对临床上有用的CMR参数进行严重程度分级的标准化，以使与推荐临床医生的交流更加清楚和容易，并且可能有助于改善患者护理水平。为此，欧洲心血管影像协会（EACVI）成立了这个专家小组，对该小组进行了严格的审查，并对常用定量CMR参数的严重性分级方法达成了共识。
