There are few data on practice patterns and trends for cardiovascular magnetic resonance (CMR) in pediatric and congenital heart disease. The Society for Cardiovascular Magnetic Resonance (SCMR) sought to address this deficiency by performing an international survey of CMR centers.
Surveys consisting of 31 (2014) and 33 (2018) items were designed to collect data on the use of CMR for the evaluation of pediatric and congenital heart disease patients. They were sent to all SCMR members in 2014 and 2018. One response per center was collected.
There were 93 centers that responded in 2014 and 83 in 2018. The results that follow show data from 2014 and 2018 separated by a dash. The median annual number of pediatric/congenital CMR cases per center was 183-209. The median number of scanners for CMR was 2-2 (range, 1-8) with 58-63% using only 1.5T scanners and 4-4% using only 3T scanners. The mean number of attending/staff reading CMRs was 3.7-2.6; among them, 52-61% were pediatric or adult cardiologists and 47-38% were pediatric or adult radiologists. The median annual case volume per attending was 54-86. The median number of technologists per center doing CMRs was 4-5. The median scanner time allocated for a non-sedated examination was 75-75 min (range, 45-120). Among the 21 centers responding to both surveys, the mean annual case volume increased from 320 in 2014 to 445 in 2018; 17 (81%) of the centers had an increase in annual case volume. For this subgroup, the median attending/staff per center was 4 in both 2014 and 2018. The median scanner time allotted per study was unchanged at 90 min. The mean time for an attending/staff physician to perform a typical CMR examination including reporting was 143-141 min.
These survey data provide a novel comprehensive view of CMR practice in pediatric and congenital heart disease. This information is useful for internal benchmarking, resource allocation, addressing practice variation, quality improvement initiatives, and identifying unmet needs.
关于儿科和先天性心脏病患者心血管磁共振（CMR）的应用模式和趋势，目前数据有限。为此，心血管磁共振学会（SCMR）对 CMR 中心进行了一项国际调查。
该调查由 31 项（2014 年）和 33 项（2018 年）内容组成，旨在收集用于评估儿科和先天性心脏病患者的 CMR 使用数据。调查于 2014 年和 2018 年分发给所有 SCMR 成员，每个中心仅收集一份回复。
2014 年有 93 个中心做出回应，2018 年有 83 个中心做出回应。以下结果显示了 2014 年和 2018 年的数据，用破折号隔开。中心每年儿科/先天性 CMR 病例中位数为 183-209 例。CMR 扫描仪中位数为 2-2 台（范围为 1-8 台），58-63%的中心仅使用 1.5T 扫描仪，4-4%的中心仅使用 3T 扫描仪。阅读 CMR 的主治医生/员工人数中位数为 3.7-2.6 人；其中 52-61%是儿科或成人心脏病专家，47-38%是儿科或成人放射科医生。主治医生/员工每年人均病例数中位数为 54-86 例。做 CMR 的技师人数中位数为 4-5 人。非镇静检查的中位扫描仪时间为 75-75 分钟（范围为 45-120 分钟）。在对两次调查均做出回应的 21 个中心中，年度病例量平均值从 2014 年的 320 例增加到 2018 年的 445 例；17 个（81%）中心的年度病例量有所增加。对于这个亚组，2014 年和 2018 年中心的中位主治医生/员工人数均为 4 人。每次研究分配的中位扫描仪时间保持不变，为 90 分钟。主治医生/员工完成典型 CMR 检查（包括报告）的平均时间为 143-141 分钟。
这些调查数据为儿科和先天性心脏病患者的 CMR 应用模式提供了新颖而全面的视角。这些信息可用于内部基准测试、资源分配、解决实践差异、质量改进举措以及识别未满足的需求。
