Voxel-wise Bayesian Estimation for Multi-Population Positronium Lifetime Imaging
Berkin Uluutku, Narendra Rathod, Giulianno Gasparato +4
Positronium lifetime imaging (PLI) provides local annihilation environment data beyond conventional activity imaging. Existing approaches, however, often estimate lifetime paramete…
First Positronium Lifetime Imaging using Mn and Co with a plastic-based PET scanner
Manish Das, Sushil Sharma, Ermias Yitayew Beyene +45
Positronium Lifetime Imaging (PLI) extends positron emission tomography by using the lifetime of positronium atoms as a probe of tissue molecular architecture. In this work, we rep…
Particle spectra in the integrated hydrokinetic model at RHIC Beam-Energy-Scan energies
Narendra Rathod, Yuri Sinyukov, Musfer Adzhymambetov +1
We study light-hadron production in Au+Au collisions at GeV using an extended Integrated HydroKinetic Model (iHKMe). Focusing on transverse momentum spectr…
First Positronium Lifetime Imaging with Scandium-44 on a Long Axial Field-of-view PET/CT
Lorenzo Mercolli, William M. Steinberger, Pascal V. Grundler +12
Purpose: 44Sc has been successfully produced, synthesized, labeled and first-in-human studies were conducted some years ago. The decay properties of 44Sc, together with being close…
Positronium Lifetime Imaging with the Biograph Vision Quadra using 124I
Lorenzo Mercolli, William M. Steinberger, Narendra Rathod +7
Purpose: Measuring the ortho-positronium (oPs) lifetime in human tissue bears the potential of adding clinically relevant information about the tissue microenvironment to conventio…
