Feasibility study of the positronium lifetime imaging with the Biograph Vision Quadra and J-PET tomographs
Szymon Parzych, Szymon Niedźwiecki, Ermias Yitayew Beyene +39
Background: After its first ex-vivo and in-vivo demonstration, Positronium Lifetime Imaging (PLI) has received considerable interest as a potential new diagnostic biomarker. High s…
Positronium Imaging: History, Current Status, and Future Perspectives
PaweÅ Moskal, Aleksander Bilewicz, Manish Das +11
Positronium imaging was recently proposed to image the properties of positronium atoms in the patient body. Positronium properties depend on the size of intramolecular voids and ox…
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…
