Innovative 3D-imaging technique captures brain damage linked to Alzheimer's disease

Researchers used a novel 3D mapping technique to analyze MRI data from Alzheimer's patients and those with mild cognitive impairment (MCI). The study found progressive brain atrophy in both groups, but MCI patients showed more cortical damage characteristic of Alzheimer's. This innovative method outperforms existing 3D imaging techniques.
