Software as good as hardware for PET gating

Published in MPW, 17 May 2016

Researchers in the US have demonstrated that software is as good as, if not better than, hardware when it comes to filtering out patient motion during PET. In blind tests of software- and hardware-gated PET images, reviewers could spot no difference most of the time, and when differences were seen, software gating was more likely to be rated as superior. The researchers believe the results could be a “game changer” for software-gated PET, which they say provides an easy and low-cost way to better PET scans (Radiology doi: 10.1148/radiol.2016152105).

PET is a technique for imaging metabolic processes using a positron-emitting tracer that’s 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. […]
