Web12 aug. 2016 · One dog (Ozzie) moved too much during scanning, polluting the fMRI data, so his results were not used in subsequent analyses. In live-scanning, the other 12 subjects received between 12 and 16 presentations of the horse-food pairing, 15 and 20 presentations of the brush pairing, and between 60 and 80 presentations of the car. WebBy using hybrid 18 F-FDG PET/fMRI, we aim to obtain spatially and temporally matched structural, functional, and metabolic information of TLE patients, localize their hypometabolic regions, compare the differences of FC alteration patterns based on hypometabolic region and structural lesion, respectively, and further explore their relationships with disease …
WebThe fMRI concept builds on the earlier MRI scanning technology and the discovery of properties of oxygen-rich blood. MRI brain scans use a strong, permanent, static magnetic field to align nuclei in the brain region being studied. Another magnetic field, the gradient field, is then applied to spatially locate different nuclei.
