BACKGROUND
Cardiac magnetic resonance (CMR) imaging is the golden standard used for the diagnosis of cancer therapy-related cardiac dysfunction (CTRCD). The consistency of cardiac computed tomography (CCT) in CTRCD cases using CMR imaging is investigated in this study.
METHODS AND RESULTS
In 7 clinically confirmed CTRCD patients, focal late enhancement was confirmed on both CCT and CMR for 4 patients. Myocardial extracellular volume (ECV) values measured by CCT and CMR were elevated in all patients, suggesting the presence of diffuse myocardial damage.
CONCLUSIONS
The study findings indicated that CCT could provide adequate information about late myocardial enhancement and ECV quantification, indicating the effective evaluation of CTRCD by CCT.
背景
心脏磁共振（CMR）成像被用作诊断癌症治疗相关心功能障碍（CTRCD）的金标准。本研究旨在探究心脏计算机断层扫描（CCT）在 CMR 成像中对 CTRCD 病例的一致性。
方法和结果
在 7 例临床确诊的 CTRCD 患者中，4 例患者的 CCT 和 CMR 均证实存在局灶性晚期强化。所有患者的 CCT 和 CMR 测量的心肌细胞外容积（ECV）值均升高，提示存在弥漫性心肌损伤。
结论
研究结果表明，CCT 可以提供关于晚期心肌强化和 ECV 定量的充分信息，表明 CCT 可以有效地评估 CTRCD。
