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]

, 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°).

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

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.

Association of Phosphorylated Tau Biomarkers With Amyloid Positron Emission Tomography vs Tau Positron Emission Tomography

JAMA Neurology, 2022
This cross-sectional study of 2 observational cohorts investigates if phosphorylated tau biomarkers are more associated with the presence of cerebral β-amyloidosis or tau neurofibrillary tangle aggregation.
