Cardiac chamber enlargement is important in the prediction of morbidity and mortality for a multitude of cardiovascular processes. Although non-electrocardiographically (ECG) gated multidetector CT is a commonly used cross-sectional imaging modality to evaluate a litany of cardiothoracic processes, a standardized method for evaluating and reporting cardiac chamber size does not exist. This has led to heterogeneity in the reporting of cardiac enlargement at routine multidetector CT with most readers often using gestalt assessment and the term , which does not implicate the chamber or chambers that are enlarged. The purpose of this review article is to highlight advantages and limitations of several techniques used to assess cardiac chamber size at non-ECG-gated multidetector CT and to provide readers with reproducible and rapid measurements to determine if cardiac chamber size is present. The long-term aim would be to promote discussions between radiologists and institutions that would result in improved accuracy and decreased variability when commenting on cardiac chamber size. © RSNA, 2019.
心脏腔室扩大对于多种心血管疾病的发病率和死亡率预测具有重要意义。尽管非心电图（ECG）门控的多排CT是一种常用的横断面成像方式，用于评估一系列心胸疾病，但目前尚无评估和报告心脏腔室大小的标准化方法。这导致在常规多排CT中报告心脏扩大时存在异质性，大多数读者通常采用整体评估和术语，而这些并不涉及扩大的腔室。这篇综述文章的目的是强调在非ECG门控多排CT中用于评估心脏腔室大小的几种技术的优缺点，并为读者提供可重复且快速的测量方法，以确定是否存在心脏腔室大小异常。长期目标是促进放射科医生和各机构之间的讨论，从而在评论心脏腔室大小方面提高准确性并减少变异性。© RSNA，2019年。
