Open cardiovascular magnetic resonance (CMR) scanners offer the potential for imaging patients with claustrophobia or large body size, but at a lower 1.0 Tesla magnetic field. There is a paucity of data in the pediatric and congenital heart disease population. This study aimed to evaluate the efficacy of open CMR for evaluation of pediatric and congenital heart disease.
This retrospective, cross-sectional study included all patients ≤18 years old or with congenital heart disease who underwent CMR on a Panorama High Field Open scanner (Philips, Best, The Netherlands) at two centers from 2012-2014. Indications for CMR, clinical questions and demographic data were extracted from the medical record and requisitions. A single experienced observer graded image quality (4-excellent, 3-adequate, 2-poor, 1-nondiagnostic), and ability to answer the clinical question (4-answer with confidence, 3-answer adequately, 2-low certainty, 1-nondiagnostic).

Open CMR scanners can effectively evaluate pediatric and congenital heart disease, including patients with claustrophobia and larger body size. Although minor artifacts may be present, the majority of clinical questions can be answered adequately, with some limitations with coronary artery imaging. Further evaluation is necessary to optimize protocols and image quality.
