Simulating effects of brain atrophy in longitudinal PET imaging with an anthropomorphic brain phantom
In longitudinal positron emission tomography (PET), the presence of volumetric changes over time can lead to an overestimation or underestimation of the true changes in the quantified PET signal due to the partial volume effect (PVE) introduced by the limited spatial resolution of existing PET cameras and reconstruction algorithms. Here, a 3D-printed anthropomorphic brain phantom with attachabl...

متن کاملAn anthropomorphic polyvinyl alcohol brain phantom based on Colin27 for use in multimodal imaging.
PURPOSE In this paper, the method for the creation of an anatomically and mechanically realistic brain phantom from polyvinyl alcohol cryogel (PVA-C) is proposed for validation of image processing methods such as segmentation, reconstruction, registration, and denoising. PVA-C is material widely used in medical imaging phantoms because of its mechanical similarities to soft tissues. METHODS T...
متن کاملAmyloid brain PET imaging
Brain positron emission tomography (PET) has also been used over many years to diagnose neurodegenerative diseases, and has advantages over MRI due to its higher sensitivity to detect pathologies at a molecular level. While 18F-fluorodeoxyglucose (FDG) PETCT is an established imaging technique for assisting in the differential diagnosis of Alzheimer’s disease (AD) and other forms of dementia, P...
متن کاملDiagnosis of Brain Tumors Using Amino Acid Transport PET Imaging With 18F- Fluciclovine: A Comparison Study With L-Methyl-11C-Methionine PET Imaging
Objective(s): 18F-fluciclovine (trans-1-amino-3-[18F] fluorocyclobutanecarboxylic acid, [FACBC]) is an artificial amino acid radiotracer used for positron emission tomography (PET) studies, which is metabolically stable in vivo and has a long half-life. It has already been shown that FACBC-PET is useful for glioma imaging. However, there have been no reports evaluating the efficiency of FACBC-P...
