Comparison of state-of-the-art atlas-based bone segmentation approaches from brain MR images for MR-only radiation planning and PET/MR attenuation correction
Introduction: Magnetic Resonance (MR) imaging has emerged as a valuable tool in radiation treatment (RT) planning as well as Positron Emission Tomography (PET) imaging owing to its superior soft-tissue contrast. Due to the fact that there is no direct transformation from voxel intensity in MR images into electron density, itchr('39')s crucial to generate a pseudo-CT (Computed Tomography) image ...
متن کاملSimultaneous functional imaging using fPET and fMRI
CERMEP, France Brain mapping of task-associated changes in metabolism with PET has been accomplished by subtracting scans acquired during two distinct static states. We have demonstrated that PET can provide truly dynamic information on cerebral energy metabolism using constant infusion of FDG and multiple stimuli in a single experiment. We demonstrate here that the functional PET (fPET-FDG) me...
متن کاملNetworks mediating the clinical effects of pallidal brain stimulation for Parkinson's disease: a PET study of resting-state glucose metabolism.
Employing [(18)F]fluorodeoxyglucose (FDG) and PET, we have found previously that stereotaxic ablation of the internal globus pallidus (GPi) for Parkinson's disease causes resting metabolic changes in brain regions remote from the lesion site. In this study we determined whether similar metabolic changes occur in Parkinson's disease patients treated with deep brain stimulation (DBS) of the GPi. ...
متن کاملSimultaneous trimodal MR-PET-EEG imaging for the investigation of resting state networks in humans
RWTH Aachen, Germany Glucose is the principal source of energy for the brain and its relationship to neuronal activity are poorly understood. The human brain uses 80% of its energy for ongoing neural activity that occurs in isolation from any particular stimulus. A promising tool for the investigation of glucose metabolism and its relationship to neuronal activity is simultaneous trimodal MR-PE...
متن کاملA study of persistent post-concussion symptoms in mild head trauma using positron emission tomography.
BACKGROUND Complaints of persistent cognitive deficits following mild head trauma are often uncorroborated by structural brain imaging and neuropsychological examination. OBJECTIVE To investigate, using positron emission tomography (PET), the in vivo changes in regional cerebral uptake of 2-[(18)F]fluoro-2-deoxy-D-glucose (FDG) and regional cerebral blood flow (rCBF) in patients with persiste...
