Technology Backgrounder From Philips on Dementia

October 29, 2008

In the second, 48-patient study using FDG-PET images provided by the Austin Hospital (Melbourne, Australia), the software achieved better than 80% correspondence when differentiating between scans that had been expert assessed as being un-diseased, suffering from Alzheimer's, suffering from Frontotemporal Dementia or suffering from Lewy Body Dementia. This second study, involving the differential diagnosis of four disease classes, was a greater test for the software than the first study, because indications of Alzheimer's and Lewy Body Dementia occur in similar areas of the brain. Nevertheless, the software was able to differentiate between them.

Following on from the encouraging results of these studies, Philips Research is conducting additional studies involving the software in collaboration with the University of Washington (Seattle, USA).
