New gamma sensor opens door to PET-MRI compatibility

Leti, working under the EU SPADnet project, assembled and characterized a gamma sensor for positron emission tomography (PET). Unlike photomultiplier tubes, the gamma sensor is compatible with the intense magnetic fields of magnetic resonance imaging (MRI).
The development could result in combined PET-MRI scans for cancer patients, providing the functional information of a PET scan with the anatomical information of an MRI on organs for which PET and MRI cannot currently be used or are not recommended for use in combination—such as on the brain or in children.
The sensor delivers state-of-the art resolution in energy, time, and space, thanks in part to optical concentrators developed by Leti to enhance the sensor’s sensitivity.
