A study by University College London, part-funded by Alzheimer's Society's Heather Corrie Impact Fund, has found that diagnostic MRI scans for dementia can be reduced to one-third of their standard length.

MRI scans play a crucial role in accurate dementia diagnosis, helping to rule out other causes of symptoms and diagnose the type of dementia. Reducing scan time has been hailed as a step towards ending the "postcode lottery in dementia diagnosis".

Cutting the time for diagnostic MRI scans for dementia has been described as a step towards ending 'the postcode lottery in dementia diagnosis'.

This development is also significant for emerging disease-modifying treatments, such as lecanemab and donanemab, which require an MRI scan before starting treatment and for safety monitoring.
