PET/MR System Design

The combination of clinical MR and PET scanners has received increasing attention in recent years. In contrast to currently used PET/CT machines, PET/MR offers not only improved soft-tissue contrast and reduced ionizing radiation but also a wealth of available MR variations such as functional, spectroscopic, and diffusion tensor imaging. This combination, however, has proven to be very challenging, due to the detrimental effect of the scanners on each other’s performance. Significant progress has been made in the last 10 years to solve the various technical issues, culminating with the recent release of clinical whole-body hybrid scanners.
