Single-tracer [ 18 F]FDG PET quantification of blood–brain barrier permeability and cerebral blood flow: Validation using dual-tracer PET

Kevin J. Chung, Terry Jones, Yasser G Abdelhafez, Benjamin A. Spencer et autres

Imaging the blood–brain barrier (BBB) permeability of molecular PET tracers may allow pathway-specific assessment of the diverse transport mechanisms expressed at the BBB. However, PET quantification of BBB permeability typically requires dual-tracer protocols involving a flow tracer, increasing methodological complexity and clinical …

Monte Carlo-based scatter correction for the plastic-based modular PET scanner J-PET

Reimund Bayerlein, Manish Das, Sushil Sharma, Ramsey Derek Badawi et autres

Abstract Objective. This work presents and evaluates a Monte Carlo (MC) -based scatter correction (SC) method developed for the Jagiellonian positron emission tomography (J-PET) scanner, a modular PET system based on plastic scintillators. Approach. The algorithm employs SimSET-based simulations integrated into a …

Incorporating Tissue Composition Information in Total-Body PET Metabolic Quantification of Bone Marrow through Dual-Energy CT

Siqi Li, Benjamin A. Spencer, Yiran Wang, Yasser G. Abdelhafez et autres

Bone marrow (BM) metabolic quantification with 18F-fluorodeoxyglucose (FDG) positron emission tomography (PET) is of broad clinical significance for accurate assessment of BM at staging and follow-up, especially when immunotherapy is involved. However, current methods of quantifying BM may be inaccurate because the …
