Incorporating Tissue Composition Information in Total-Body PET Metabolic Quantification of Bone Marrow through Dual-Energy CT
Siqi Li, Benjamin A. Spencer, Yiran Wang +7
Bone marrow (BM) metabolic quantification with 18F-fluorodeoxyglucose (FDG) positron emission tomography (PET) is of broad clinical significance for accurate assessment of BM at st…
Total-Body Parametric Imaging Using Relative Patlak Plot
Siqi Li, Yasser G. Abdelhafez, Lorenzo Nardo +3
Standard Patlak plot is widely used to describe FDG kinetics for dynamic PET imaging. Whole-body Patlak parametric imaging remains constrained due to the need for a full-time input…
Feasibility of PET-enabled dual-energy CT imaging: First physical phantom and initial patient results
Yansong Zhu, Siqi Li, Zhaoheng Xie +9
X-ray computed tomography (CT) in PET/CT is commonly operated with a single energy, resulting in a limitation of lacking tissue composition information. Dual-energy (DE) spectral C…
Supplemental Transmission Aided Attenuation Correction for Quantitative Cardiac PET/MR
Mi-Ae Park, Vlad G. Zaha, Ramsey D. Badawi +1
Quantitative PET attenuation correction (AC) for combined cardiac PET/MR is a challenging problem. We propose and evaluate an AC approach that uses coincidences from a relatively w…
Multiparametric Cardiac 18F-FDG PET: Pilot Comparison of FDG Delivery Rate with 82Rb Myocardial Blood Flow
Yang Zuo, Javier E. Lopez, Thomas W. Smith +4
Myocardial blood flow (MBF) and flow reserve are usually quantified in the clinic with positron emission tomography (PET) using a perfusion-specific radiotracer (e.g. 82Rbchloride)…
Multiparametric Cardiac 18F-FDG PET in Humans: Kinetic Model Selection and Identifiability Analysis
Yang Zuo, Ramsey D. Badawi, Cameron C. Foster +3
Cardiac 18F-FDG PET has been used in clinics to assess myocardial glucose metabolism. Its ability for imaging myocardial glucose transport, however, has rarely been exploited in cl…
