Differentiation of Alzheimer disease dementia (ADD) and dementia with Lewy bodies (DLB) remains a challenge. Free-water (FW) imaging has been investigated in neurodegenerative diseases and was found to be associated with neurodegeneration and neuroinflammation. This retrospective cohort study tested whether Automated Imaging Differentiation for Dementia (AIDD), combining diffusion free-water imaging (FWI) and support vector machine, predicts ADD vs DLB with high accuracy.
Chen et al. (Mon,) studied this question.
