Liquid Xenon Detectors for Positron Emission Tomography

, 2011
PET is a functional imaging technique based on detection of annihilation photons following beta decay producing positrons. In this paper, we present the concept of a new PET system for preclinical applications consisting of a ring of twelve time ...

Development of an automated method for in-house production of sodium 18F-fluoride for injection: process validation as a step toward routine clinical application

EJNMMI Radiopharmacy and Chemistry
Background Sodium 18F-fluoride for injection can be easily cyclotron-produced and purified, as a simple inorganic salt, by adsorption/desorption onto an anion-exchange cartridge and then dispensed for clinical use.

A DNA-damage immune response assay combined with PET biomarkers predicts response to neo-adjuvant chemotherapy and survival in oesophageal adenocarcinoma

Scientific Reports, 2021
18F-fluorodeoxyglucose PET-CT may guide treatment decisions in patients with oesophageal adenocarcinoma (OAC). This study evaluated the added value of maximum standardised uptake value (SUVmax) to a novel DNA-damage immune response (DDIR) assay to ...

Cardiac Positron Emission Tomography

Journal of the American College of Cardiology, 2009
Positron emission tomography (PET) is a powerful, quantitative imaging modality that has been used for decades to noninvasively investigate cardiovascular biology and physiology. Due to limited availability, methodologic complexity, and high costs, it has long been seen as a research tool and as a reference method for validation of other diagnostic ...

Reduced Expression of Cerebral Metabotropic Glutamate Receptor Subtype 5 in Men with Fragile X Syndrome

Brain Sciences, 2020
Glutamatergic receptor expression is mostly unknown in adults with fragile X syndrome (FXS). Favorable behavioral effects of negative allosteric modulators (NAMs) of the metabotropic glutamate receptor subtype 5 (mGluR5) in fmr1 knockout (KO) mouse ...

Fibroblast activation protein expression in the tumor microenvironment is crucial in survival prediction and differentiation of recurrent gliomas: a head-to-head comparison of 68Ga-FAPI-04 and 18F-FET in PET/CT imaging

EJNMMI Radiopharmacy and Chemistry
Background The precise differentiation of recurrent glioma from treatment-related changes, such as pseudoprogression or radiation necrosis, is essential for treatment planning and remains a significant challenge.

Pre-Operative Prediction of Mediastinal Node Metastasis Using Radiomics Model Based on 18F-FDG PET/CT of the Primary Tumor in Non-Small Cell Lung Cancer Patients

Frontiers in Medicine, 2021
Purpose: We investigated whether a fluorine-18-fluorodeoxy glucose positron emission tomography/computed tomography (18F-FDG PET/CT)-based radiomics model (RM) could predict the pathological mediastinal lymph node staging (pN staging) in patients with ...
