PET-MR

Clinical utility

* No emission dose from MR

* Obvious advantage in neurology

* Unproven in other clinical role

* Potential advantage in study

mechanical trials

* Avalanche photodiode

* Potentially more loud and poorer power tenacity

* presentation is temperature dependant

* CT supplies an attenuation map but MR does not

* added issues with positioning aids

*Attenuation correction is not straightforward
