PET/MRI: Reflections Two Years After FDA Approval

June 18, 2013

This is the first in a two-part series investigating PET/MRI’s status and future two years after FDA approval. Part two examines implementation and reimbursement challenges.

When the FDA approved the Siemens Biograph mMR system two years ago, it became the first (and still only approved) machine to perform PET and MRI scans simultaneously. Philips’ hybrid system gained FDA approval soon after, allowing for similar results with sequential scanning. In those two years, the handful of research centers adopting the technology continue to struggle with learning how to integrate the system with their workflow, comparing the utility of PET/MRI versus PET/CT, and determining which organs and disease processes are best imaged with PET/MRI.
