PET-MR Dataset

Simultaneously acquired positron emission tomography and magnetic resonance data of the brain, plus joint image reconstruction code.

We are making available an in vivo PET-MR dataset used in joint reconstruction experiments in our related publication (see Figure 8 in the paper cited below).

The data were acquired on a Siemens Biograph mMr during a 10-minute brain FDG-PET scan combined with an undersampled MPRAGE MR scan.

The dataset includes MR-receive coil sensitivity maps, PET attenuation correction maps, and scatter estimates.
