Fesharaki‐Zadeh A, Cayir S, Ibrahim W, Yang Y, Gallezot J, Naganawa M, Wu Y, Toyonaga T, Sadabad F, O'Dell R, Pittman B, Nabulsi N, Strittmatter S, Carson R, Huang Y, van Dyck C, Mecca A, Matuskey D. Synaptic density imaging in behavioral variant frontotemporal dementia: A comparison of 18F‐SynVesT‐1 and 18F‐FDG PET. Alzheimer's & Dementia 2026, 22: e71283. PMID: 41954197, PMCID: PMC13063251, DOI: 10.1002/alz.71283.Peer-Reviewed Original ResearchThis study investigates synaptic density imaging in behavioral variant frontotemporal dementia, showing that SV2A PET detects more pronounced synaptic loss than glucose hypometabolism using FDG PET, aiding early diagnosis and monitoring.Variance reduction with synaptic density imaging in Parkinson’s disease using direct-4D PET image reconstruction
Gravel P, Gallezot J, Fontaine K, Matuskey D, Carson R. Variance reduction with synaptic density imaging in Parkinson’s disease using direct-4D PET image reconstruction.
