Optimization of PET/MR Scan Protocol With Introduction of a 3D T2 Dixon Sequence
Purpose or Case Report: PET/MRI is a relatively new imaging modality whose efficacy is still being determined. One of the major draws to PET/MR over PET/CT is the reduction in radiation exposure to patients. This is especially desirable in the pediatric population due to the likelihood of multiple exposures during their lifetime, and the increased sensitivity they have to radiation. A typical whole body PET/CT exam can take about 30 minutes, whereas a typical whole body PET/MR exam takes about 90 minutes at our institution. The introduction of a new 3D T2 Dixon technique sequence for PET/MR has the potential of decreasing total scan time significantly, however maintaining current image quality and diagnostic value is critical. Our objective is to test out this new sequence to see whether scan times are reduced and if it is a viable diagnostic replacement for our current T2 sequence.
