Overview

• The ADMIRA clinic study compared accelerated and standard brain MRI in 92 outpatients during routine evaluations.
• Three neuroradiologists, blinded to technique, judged the faster images as diagnostically comparable to standard-of-care scans.
• The protocol reduced time in the scanner by roughly two thirds, which the team says could allow at least twice as many dementia scans per day.
• Alzheimer’s Society says shorter, cheaper scans could ease the UK’s postcode disparities in access to diagnostic imaging.
• With new drugs such as lecanemab and donanemab requiring baseline and safety MRIs, the researchers plan multi-scanner, multi-centre validation to enable broader rollout.
