MRI links hearing loss to increased dementia risk
By Kate Madden Yee
MRI has shown that hearing loss may increase dementia risk in seniors not yet cognitively impaired in ways distinct from those that tend to be associated with conditions such as Alzheimer's and cerebrovascular disease.

MRI reveals effects of risk factors on vulnerable brain regions
By Kate Madden Yee
MRI shows the effects particular risk factors such as diabetes, air pollution, and frequency of alcohol use have on "higher-order" brain regions located in the cerebral cortex, researchers have found.
March 27, 2024
To the left of the figure, the red-yellow color denotes the regions that degenerate earlier than the rest of the brain and are vulnerable to Alzheimer’s disease. These brain areas are higher-order regions that process and combine information coming from our different senses. To the right of the figure, each dot represents the brain data from one UK Biobank participant. The overall curve shows that, in these particularly fragile regions of the brain, there is accelerated degeneration with age. Image courtesy of Gwenaëlle Douaud, PhD, and Jordi Manuello, PhD.

AI spots unidentified brain tumor on PET imaging
By Will Morton
An AI algorithm designed for brain PET imaging found a glioblastoma in a patient that had gone undetected by physicians.
February 20, 2024
Baseline scan (A), segmentation results (B), and follow-up scan (C) from patient with molecular glioblastoma. Baseline MRI showed FLAIR hyperintensities in left thalamus and frontoparietal region (white arrowheads). In contrast to expert segmentation, in which only left thalamic region showed slightly increased uptake (red contour), AI algorithm identified additional frontoparietal lesion on baseline PET that subsequently progressed to contrast-enhancing and metabolically active lesion (red arrowheads).
