Multiple sclerosis is a disease of the central nervous system that manifests itself in changes (lesions) primarily in the brain. As yet, there is no cure for MS, but it can be effectively treated.
Positron emission tomography is an imaging technique that uses radiation to show activity within the body on a cellular level. People more commonly refer to it as a PET scan.
To determine how aggressive someone's cancer is, doctors look for abnormalities in slices of biopsied tissue on a slide. But this 2D method makes it hard to properly diagnose borderline cases. Now a team led by the University of Washington has developed a new, non-destructive method that images entire 3D biopsies instead of just a slice.
A new automated system that involves deep learning technology enables the detection of COVID-19 lesion via the analysis of a computed tomography (CT) scan. This system, described in a study published in the journal Computers in Biology and Medicine, has been carried out by researchers of the UB, the EURECAT Technology Centre of Catalonia, and the Computing Vision Center (CVC).
A modeling study found that very small number of deaths averted from breast cancer may be eclipsed by cost and potential harms of overdiagnosis when annual mammography screening is extended past age 75 years.
