Radiochemistry for positron emission tomography
Nature Communications, 2023 AbstractPositron emission tomography (PET) constitutes a functional imaging technique that is harnessed to probe biological processes in vivo. PET imaging has been used to diagnose and monitor the progression of diseases, as well as to facilitate drug development efforts at both preclinical and clinical stages.

Positron-emission tomography [PDF]
IEEE Signal Processing Magazine, 1997 We review positron-emission tomography (PET), which has inherent advantages that avoid the shortcomings of other nuclear medicine imaging methods. PET image reconstruction methods with origins in signal and image processing are discussed, including the potential problems of these methods. A summary of statistical image reconstruction methods, which can

Positron Emission Tomography [PDF]
, 2006 Positron emission tomography (PET) is based on the detection in coincidence of the two 511-keV annihilation radiations that originate from β + -emitting sources, such as the patient containing β + -emitting radioactivity. Positrons are annihilated in body tissue and produce two 511-keV annihilation photons that are emitted in opposite directions (180°).

Perspectives for Positron Emission Tomography with RPCs [PDF]
, 2002 In this study we address the feasibility and main properties of a positron emission tomograph (PET) based on RPCs. The concept, making use of the converter-plate principle, takes advantage of the intrinsic layered structure of RPCs and its simple and economic construction.

QED and Fundamental Symmetries in Positronium Decays [PDF]
Acta Phys. Polon. B50 (2019) 1319, 2019 We discuss positronium decays with emphasis on tests of fundamental symmetries and the constraints from measurements of other precision observables involving electrons and photons.

18F-fluorodeoxyglucose positron emission tomography / computed tomography in primary Ewing sarcoma of the lung [PDF]
Srpski Arhiv za Celokupno Lekarstvo, 2022 Introduction. Ewing sarcoma is rare in medical practice, and evaluating positron emission tomography / computed tomography (PET/CT) imaging of soft tissue Ewing sarcoma is a challenge. Primary Ewing sarcoma of the lung is an infrequent diagnosis.
