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). {read more here}
