Purpose Since the 1990s, PET has been successfully combined with MR or CT systems. In
the past years, especially PET systems have seen a trend towards an enlarged axial field of …

In last decades hybrid imaging, combining molecular and anatomical data in a unique,
synergistic approach, has thoroughly changed the face of medical diagnostics [1, 2]. In …

Our purpose was to evaluate the performance of the Biograph Vision Quadra PET/CT
system. This new system is based on the Biograph Vision 600, using the same silicon …

Purpose To investigate the performance of the new long axial field-of-view (LAFOV)
Biograph Vision Quadra PET/CT and a standard axial field-of-view (SAFOV) Biograph Vision …

In vivo assessment of cancer and precise location of altered tissues at initial stages of
molecular disorders are important diagnostic challenges. Positronium is copiously formed in …

Background Gallium 68 (68Ga)–labeled fibroblast-activation protein inhibitor (FAPI) has
recently been introduced as a promising tumor imaging agent. Purpose To compare 68Ga …

Purpose To investigate the kinetics of 18 F-fluorodeoxyglucose (18 F-FDG) by positron
emission tomography (PET) in multiple organs and test the feasibility of total-body …

The purpose of the presented research is estimation of the performance characteristics of
the economic total-body Jagiellonian-PET system (TB-J-PET) constructed from plastic …

Positronium is abundantly produced within the molecular voids of a patient's body during
positron emission tomography (PET). Its properties dynamically respond to the submolecular …

Abstract Purpose [18 F] FAPI-42 is a new fibroblast activation protein (FAP)-specific tracer
used for cancer imaging. Here, we describe the optimal acquisition time and in vivo …
