Task-evoked simultaneous FDG-PET and fMRI data for measurement of neural metabolism in the human visual cortex

Abstract: Understanding how the living human brain functions requires sophisticated in vivo neuroimaging technologies to characterise the complexity of neuroanatomy, neural function, and brain metabolism. Fluorodeoxyglucose positron emission tomography (FDG-PET) studies of human brain function have historically been limited in their capacity to measure dynamic neural activity. Simultaneous [18 F]-FDG-PET and functional magnetic resonance imaging (fMRI) with FDG infusion protocols enable examination of dynamic changes in… Show more

“…To prepare the BIDS dataset, the open source conversion tool Heudiconv [ 20 ] was used to organize the imaging data into structured directory layouts, and the dcm2niix converter [ 21 ] was used to convert image data from dicom to NIfTI format. Following the approach in our previous article [ 28 ], we applied scripts to (i) remove personal identifiable information from the raw PET dicom header, (ii) add custom json sidecar files to the PET raw data and reconstructed image data, and (iii) generate plasma radioactivity files. Refer to [ 19 ] for these scripts.…”

“…Simultaneous MR-PET is a nascent technique, opening up many opportunities for scientific discovery, methods development, and signal optimization of dual-modality data. Although few imaging facilities worldwide currently possess the infrastructure and technical skill to acquire fPET-fMRI data, the rapid increase in publication (e.g., [ 5–7 , 10–12 , 15 , 28 , 40 ]) and reuse metrics of publicly available datasets [ 41 , 42 ] attests to the value that the international neuroscience community places on this novel data type. The Monash DaCRA fPET-fMRI dataset is the only publicly available dataset that allows comparison of radiotracer administration protocols for fPET-fMRI.…”
