   Episode 26: Standardizing opportunistic osteoporosis screening across different CT scan settings (opens the original)

   Episode notes

   Read excerpt

   This episode explores a study from Seoul National University Bundang Hospital in South Korea on opportunistic osteoporosis screening, which reads bone density off the spine in routine chest CT scans. Using nearly six hundred patients each scanned at two different tube voltages, the team built a model that converts those readings back to a single common reference, regardless of scanner settings or spinal level. The converted diagnostic thresholds closely matched directly measured ones, pointing t

   Episode 25: Estimating brain age from MRI to flag accelerated aging and cognitive decline (opens the original)

   Episode notes

   Read excerpt

   This episode discusses a study from Johns Hopkins University in the United States that introduces a brain age predictor from MRI, designed to stay accurate across different scanners and cohorts. The model estimates a person's age from a brain scan to within about four years, and holds that accuracy on an independent external dataset. The gap between predicted and actual age rose steadily from healthy adults to mild cognitive impairment to dementia, and tracked cognitive test scores, supporting i
