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.
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.
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.
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.
研究英国心血管磁共振（CMR）的服务提供情况。在医疗保健中，公平获得诊断成像至关重要。CMR 在英国广泛可用，但可能存在区域差异。
2019 年，英国心血管磁共振学会通过电子调查向英国所有 CMR 单位的服务负责人发送了一份调查，要求提供 2017 年和 2018 年的数据。根据地区对回复进行分析，并结合人口统计数据进行解释。
调查回复率为 100%（82 个单位）。2017 年进行了 100386 次临床扫描，2018 年进行了 114967 次（1 年增长 15%，与 2008 年数据相比增长 5 倍）。2018 年，总体上每百万人口有 1731 次 CMR 扫描，存在显著的区域差异，例如伦敦有 4256 次/百万，而威尔士有 396 次/百万。每个单位的临床扫描中位数为 780，IQR 373-1951，范围 98-10000，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，北爱尔兰的中位数为 180 天。25 个单位（30%）报告平均选择性等待时间超过 6 周，8 个单位（10%）超过 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%的单位为起搏器和除颤器患者提供 CMR 服务。
这项调查提供了一个独特的、当代的全国 CMR 服务提供情况的深入了解，10 年来 CMR 使用量增长了 5 倍，这是显著的，但在英国各地存在异质性，一些地区的使用率仍然较低或等待时间较长，这可能引起临床关注。
