Combined PET and MRI core facility

Operational manager: Eric BARDINET (Engineer)
A hybrid PET/MR scanner is available in the nuclear medicine department of the hospital La Pitié-Salpêtrière. Combining nuclear imaging with Magnetic Resonance Imaging (MRI) allows acquiring anatomical, functional and molecular images, thus providing a good anatomical reference for a better diagnosis, a shorter time spent in the scanner for the patient as well as a reduced radiation dose. This GE SIGNA integrated PET/MR system allows simultaneous PET and 3T MR imaging without moving the subject in addition to being able to measure the time of flight of the PET emission data. The combination of PET and MR imaging raises new methodological challenges, like photon attenuation correction, but also offers new opportunities such as motion correction, MR-guided PET image reconstruction and multi-parametric imaging.
