Use of Specially Designed Pediatric MR Coils on Clinical Scanners

The safety and the clinical efficacy/equivalence of two pediatric 1.5T coils will be evaluated/demonstrated in two phases. Patient safety and image quality will be evaluated/demonstrated in Phase One by collecting images on healthy participants using a combination of the existing commercially available coils and the new coils. Clinical efficacy/equivalence will be evaluated/demonstrated in Phase Two by collecting standard MRI exams in pediatric patients. In Phase Two, the imaging data for a given patient will be collected by one of the two following scenarios : 1) the clinically ordered exams will be completed using a combination of the existing commercially available coils and new coil, with the images from each directly compared, or 2) the clinically ordered scans will be collected using one of the new coils and the images compared to historical de-identified MR exam, age and gender matched patient data (which were acquired using the existing commercially available coils). Results of Phase One will be reported to the IRB. Phase Two will not begin until the IRB has reviewed the results of Phase One and approved the commencement of Phase Two.
