Pediatric patients with cardiac implantable electronic devices (CIEDs) are generally contraindicated for MRI exams. Previous work in the adult population suggests that RF heating strongly depends on the patient’s position and orientation within the MRI scanner. The objective of this work was to evaluate in silico several pediatric patient-positions within the MRI scanner as methods to reduce RF-heating.
