Non-electrocardiographic (ECG)-gated computed tomography (CT) of the chest is one of the most commonly performed imaging studies. Although the heart is included in every CT study, cardiac findings are commonly underreported in radiology reports. Left ventricular size is one of the most important prognostic markers in multiple cardiac diseases and can be measured on almost all non-ECG-gated multidetector chest CT studies. This review will discuss the available evidence on different measurements of left ventricular size obtained on non-ECG-gated CT of the chest. Measurement thresholds, technical issues, and potential problems are emphasized, with practical recommendations.
胸部非心电图门控计算机断层扫描（CT）是最常进行的影像学研究之一。虽然心脏包含在每一次 CT 研究中，但心脏发现通常在放射学报告中报告不足。左心室大小是多种心脏疾病中最重要的预后标志物之一，几乎可以在所有非心电图门控多排胸部 CT 研究中测量。这篇综述将讨论在胸部非心电图门控 CT 上获得的左心室大小不同测量方法的现有证据。强调了测量阈值、技术问题和潜在问题，并提出了实用建议。
