Cardiac magnetic resonance (CMR) imaging benefits from a large field of view, but consequently captures incidental extra-cardiac findings (IEFs). There is a relative paucity of data for CMR in this regard. Our objectives were to assess the frequency and significance of IEFs reported from clinically indicated CMR scans, and additionally to ascertain if reporting rates differed between radiologist and cardiologist in a 'real-world' setting.
A total of 714 patients were included for the study. All patients were referred to a single tertiary cardiac unit for clinically indicated scans. The clinical reports were retrospectively reviewed for reported IEF, and classified as 'minor', or 'major' depending on the need of further investigation or clinical correlation. A total of 180 IEFs were reported in 154 (21.6%) patients. Ninety IEFs were considered minor, and 90 major. Of the latter, eight (1.1%) were considered highly significant. Two hundred scans were reported by a consultant radiologist, and 514 by cardiologists. There was no significant difference in the rates of IEF reporting between the two specialties (P = 0.38).
IEFs are common, requiring further investigation in a substantial minority. The incidence of highly significant findings in this study was low (∼1%), and similar to the reported incidence in the computed tomography literature. No significant difference was found between the reporting rates of IEFs between different specialties.
心脏磁共振（CMR）成像受益于大视野，但会因此捕获偶然的心脏外发现（IEFs）。在这方面，CMR 的相关数据相对较少。我们的目的是评估从临床指征性 CMR 扫描中报告的 IEFs 的频率和意义，并进一步确定在“真实世界”环境中，放射科医生和心脏病专家之间的报告率是否存在差异。
共纳入 714 例患者进行研究。所有患者均因临床指征被转诊至一家单一的三级心脏中心进行扫描。对临床报告进行回顾性审查，以报告 IEF，并根据进一步调查或临床相关性的需要将其分类为“次要”或“主要”。在 154 名（21.6%）患者中报告了 180 例 IEF。90 例 IEF 被认为是次要的，90 例是主要的。后者中有 8 例（1.1%）被认为具有高度重要性。200 份扫描报告由顾问放射科医生撰写，514 份由心脏病专家撰写。这两个专业之间的 IEF 报告率没有显著差异（P = 0.38）。
IEFs 很常见，需要对相当一部分患者进行进一步调查。在这项研究中，高度显著发现的发生率较低（约 1%），与 CT 文献中报道的发生率相似。不同专业之间的 IEF 报告率没有发现显著差异。
