Cardiovascular magnetic resonance is successfully feasible in many patients aged 3 to 8 years without general anesthesia or sedation

Abstract Objectives Patients younger than 8 years are usually examined by cardiovascular magnetic resonance (CMR) under general anesthesia (GA) or sedation without intubation. Therefore, we sought to study the feasibility of CMR in patients aged 3 to 8years without GA or sedation. Patients Data sets of 71 consecutive patients aged 3 to 8years were studied retrospectively. Design The total cohort was divided into 2 groups: a no-GA or sedation without intubation group (no-GA or sedation) and a GA or sedation without intubation group (GA or sedation). Measurements The patients' age, scan durations for each group, successfully answered clinical question, and number of sequences per study were compared between both groups. Main results Scan duration in the no-GA or sedation group (n=44) was 35± 20minutes, and that in the GA or sedation group (n=27) was 60± 31minutes ( P P =.29). Conclusion CMR in patients aged 3 to 8years is usually successfully feasible without GA or sedation.
