Background 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. Methods 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. Results 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. Conclusion 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.
