Success for preclinical PET-MRI system

Published in MPW, 10 Apr 2015

Tests of a system that combines the benefits of both PET and MRI have been successful, according to a group of researchers in Germany and the UK. The system is currently in the pre-clinical phase, but promises to improve diagnosis by offering simultaneous insight into a subject’s anatomy and metabolic processes (Phys. Med. Biol. 60 2231).

PET is a technique for imaging metabolic processes in the body that requires a positron-emitting tracer to be introduced into the body. The emitted positrons interact with electrons in tissue, generating a pair of gamma rays that can be recorded on a detector – in turn revealing the exact position of the tracer. […]
