Objectives To examine service provision in cardiovascular magnetic resonance (CMR) in the UK. Equitable access to diagnostic imaging is important in healthcare. CMR is widely available in the UK, but there may be regional variations. Methods An electronic survey was sent by the British Society of CMR to the service leads of all CMR units in the UK in 2019 requesting data from 2017 and 2018. Responses were analysed by region and interpreted alongside population statistics. Results The survey response rate was 100% (82 units). 100 386 clinical scans were performed in 2017 and 114 967 in 2018 (15% 1-year increase; 5-fold 10-year increase compared with 2008 data). In 2018, there were 1731 CMR scans/million population overall, with significant regional variation, for example, 4256 scans/million in London vs 396 scans/million in Wales. Median number of clinical scans per unit was 780, IQR 373–1951, range 98–10 000, with wide variation in mean waiting times (median 41 days, IQR 30–49, range 5–180); median 25 days in London vs 180 days in Northern Ireland). Twenty-five units (30%) reported mean elective waiting times in excess of 6 weeks, and 8 (10%) ≥3 months. There were 351 consultants reporting CMR, of whom 230 (66%) were cardiologists and 121 (34%) radiologists; 81% of units offered a CMR service for patients with pacemakers and defibrillators. Conclusions This survey provides a unique, contemporary insight into national CMR delivery with 100% centre engagement. The 10-year growth in CMR usage at fivefold has been remarkable but heterogeneous across the UK, with some regions still reporting low usage or long waiting times which may be of clinical concern. All data relevant to the study are included in the article or uploaded as supplemental information.

英国心血管磁共振服务提供的区域差异

目的 调查英国心血管磁共振 (CMR) 的服务提供情况。公平获得诊断成像在医疗保健中很重要。CMR 在英国广泛使用，但可能存在地区差异。方法 英国 CMR 协会于 2019 年向英国所有 CMR 单位的服务负责人发送了一份电子调查，要求提供 2017 年和 2018 年的数据。按地区分析答复，并与人口统计数据一起解释。结果调查回复率为100%（82个单位）。2017 年进行了 100 386 次临床扫描，2018 年进行了 114 967 次（1 年增加 15%；与 2008 年数据相比，10 年增加 5 倍）。2018 年，总体上有 1731 次 CMR 扫描/百万人口，存在显着的区域差异，例如，伦敦为 4256 次/百万，威尔士为 396 次/百万。每单位临床扫描的中位数为 780，IQR 373-1951，范围 98-10 000，平均等待时间差异很大（中位数 41 天，IQR 30-49，范围 5-180）；伦敦的中位数为 25 天，北爱尔兰为 180 天）。25 个单位 (30%) 报告的平均选择性等待时间超过 6 周，8 个 (10%) ≥3 个月。有 351 名顾问报告了 CMR，其中 230 名（66%）是心脏病专家，121 名（34%）是放射科医生；81% 的单位为配备起搏器和除颤器的患者提供 CMR 服务。结论 本调查以 100% 的中心参与度提供了对全国 CMR 交付的独特、现代的见解。CMR 使用量在 10 年中增长了 5 倍，在整个英国是显着的，但差异很大，一些地区仍然报告使用率低或等待时间长，这可能是临床问题。
