Positron emission tomography [PDF]
, 2006 Positron Emission Tomography (PET) is a method for measuring biochemical and physiological processes in vivo in a quantitative way by using radiopharmaceuticals labelled with positron emitting radionuclides such as 11C, 13N, 15O and 18F and by measuring ...

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 ...

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.

Radiomics Analysis of Contrast-Enhanced CT Predicts Survival in Clear Cell Renal Cell Carcinoma
Frontiers in Oncology, 2021 PurposeTo develop and validate the radiomics nomogram that combines clinical factors and radiomics features to estimate overall survival (OS) in patients with clear cell renal cell carcinoma (ccRCC), and assess the incremental value of radiomics for OS ...

Image reconstruction method for dual-isotope positron emission tomography [PDF]
Journal of Instrumentation, Volume 16, January 2021, P01035, 2021 We developed a positron emission tomography (PET) system for multiple-isotope imaging. Our PET system, named multiple-isotope PET (MI-PET), can distinguish between different tracer nuclides using coincidence measurement of prompt gamma-rays, which are emitted after positron emission.
