PET Clin. 2025 Jan;20(1):1-10. doi: 10.1016/j.cpet.2024.09.014. Epub 2024 Oct 30.

Abstract

This review examines the role of metabolic connectivity based on fluorodeoxyglucose-PET in understanding brain network organization across neurologic disorders, with a focus on neurodegenerative diseases. The article explores key methodologies for metabolic connectivity study and highlights altered connectivity patterns in Alzheimer's, Parkinson's, frontotemporal dementia, and other conditions. It also discusses emerging applications, including single-subject analyses and brain-organ interactions.

Keywords: Brain connectivity; FDG; Fluorodeoxyglucose; Metabolic connectivity; Neuroimaging; PET.
