Abstract

Purpose To determine the prevalence of clinically relevant extracardiac findings at cardiac CT and MRI examinations from a multicenter, multinational MR/CT registry and the relationship of prevalence with examination indications and patient characteristics. Materials and Methods This was a retrospective analysis of data from the European Society of Cardiovascular Radiology MR/CT Registry. Data from 208 506 cardiac CT examinations (median patient age, 66 years [IQR, 55-77]; 121 617 [58.33%] male patients) and 228 462 cardiac MRI examinations (median patient age, 57 years [IQR, 42-69]; 145 792 [63.81%] male patients) entered into the registry between January 2011 and November 2023 were analyzed. Clinically relevant extracardiac findings were defined as findings requiring follow-up examinations or influencing clinical management. The association of examination indication and patient characteristics, including age, with prevalence of extracardiac findings was evaluated using incidence rate ratios (IRRs) derived from multivariable Poisson regression models. Results The prevalence of clinically relevant extracardiac findings was 3.28% (6832 of 208 506) at cardiac CT and 1.50% (3421 of 228 462) at cardiac MRI examinations. Extracardiac findings were more common at CT examinations performed for transcatheter aortic valve replacement (IRR, 2.07; P < .001) and structural heart disease (IRR, 1.44; P < .001) compared with CT performed for coronary artery disease (IRR, 1; reference). Extracardiac findings were more common at MRI examinations performed for myocarditis (IRR, 1.36; P < .001) and structural heart disease (IRR, 1.16; P < .001) than for coronary artery disease. Older patient age was also significantly associated with higher prevalence of extracardiac findings, with an IRR for both CT and MRI examinations of 1.02 (P < .001). Conclusion Data from the multicenter, multinational MR/CT registry indicate that clinically relevant extracardiac findings are present at cardiovascular CT and MRI examinations, and the prevalence of these findings is associated with examination indication and patient age.

心脏成像中与临床相关的心外发现:来自欧洲 MR/CT 登记处的启示。
目的 通过一项多中心、跨国 MR/CT 注册研究确定心脏 CT 和 MRI 检查中临床相关心外检查结果的发生率,以及发生率与检查适应症和患者特征之间的关系。材料和方法 这是对欧洲心血管放射学会 MR/CT 登记数据的回顾性分析。分析了 2011 年 1 月至 2023 年 11 月期间登记的 208 506 例心脏 CT 检查(患者年龄中位数为 66 岁 [IQR,55-77];121 617 例 [58.33%] 男性患者)和 228 462 例心脏 MRI 检查(患者年龄中位数为 57 岁 [IQR,42-69];145 792 例 [63.81%] 男性患者)的数据。与临床相关的心外检查结果被定义为需要进行随访检查或影响临床治疗的结果。使用多变量泊松回归模型得出的发病率比(IRRs)评估了检查指征和患者特征(包括年龄)与心外检查结果发生率的关系。结果 在心脏 CT 和心脏 MRI 检查中,临床相关心外检查结果的发生率分别为 3.28%(208 506 例中的 6832 例)和 1.50%(228 462 例中的 3421 例)。经导管主动脉瓣置换术(IRR,2.07;P <.001)和结构性心脏病(IRR,1.44;P <.001)与冠状动脉疾病(IRR,1;参考)的 CT 检查相比,心外检查结果更常见。与冠状动脉疾病相比,心肌炎(IRR,1.36;P<.001)和结构性心脏病(IRR,1.16;P<.001)的核磁共振检查更常见心外检查结果。患者年龄越大,心外检查结果的发生率也越高,CT 和 MRI 检查的 IRR 均为 1.02(P < .001)。结论 来自多中心、跨国 MR/CT 登记处的数据表明,心血管 CT 和 MRI 检查中存在临床相关的心外检查结果,这些结果的发生率与检查适应症和患者年龄有关。关键词心脏成像技术、意外发现、核磁共振成像、CT 血管造影、CT、心脏病 本文有补充材料。© RSNA, 2024.
