Evaluation of 18F FDG-PET/CT in Patients with Gastric Signet Ring Cell Carcinoma : Correlation with GLUT-1 Expression and Histologic Finding
… ring cell carcinoma (GSRC) is known to have low FDG uptake. The aim of the study was to investigate the relation between FDG uptake and glucose transporter-1 (GLUT-1) expression in GSRC patients. MATERIALS AND METHODS: Forty patients (28 men, mean age 54±12) with histologically confirmed GSRC who …

PRECLINICAL PET IMAGING FOR TUMOUR CHARACTERIZATION: FOCUS ON HYPOXIA AND INFLAMMATION
… hypoxic radiopharmaceutical recently developed, [18F]FAZA and [64Cu]ATSM at two different times, using PET and autoradiography. In parallel, an in vitro evaluation of specific hypoxic markers such as carbonic anhydrase IX and cupper transporters (Ctr-1 and ATP7B) was performed. In FaDu model we …

Atherosclerotic inflammation imaging using somatostatin receptor-2 positron emission tomography
… arterial inflammation can be measured by 18F-fluorodeoxyglucose (FDG) PET-computed tomography (CT), as a glucose analog, high 18F-FDG signal spillover owing to physiological myocardial muscle metabolism prevents reliable coronary interpretation. Lack of cell specificity, and the influence …

Towards Robust Radiomic Markers from Positron Emission Tomography in Cancer
[18F]-fluorodeoxyglucose positron emission tomography ([18F]-FDG PET) images contain both rich and untapped information regarding diseases such as cancer. The latter can be accessed computationally using radiomics, from which we can build new markers of disease to improve the clinical management of …

Multi-modality Imaging to Determine the Role of Calcification and Inflammation on Restenosis Rates Following Lower Limb Angioplasty
… before intervention. Tracers of inflammation (18F-FDG; fluorodeoxyglucose) and calcification (18F-NaF; sodium fluoride) are higher in restenosis following lower limb angioplasty in patients with peripheral arterial disease, and drug-coated balloons (DCB) dampen the inflammatory process, in an …

Improving Quantitative Treatment Response Monitoring With Deformable Image Registration
Quantitative imaging with 18F-FDG PET/CT has the potential to provide an in vivo assessment of response to radiotherapy (RT). However, comparing tissue tracer uptake in longitudinal studies is often confounded by variations in patient setup and potential treatment induced gross anatomic changes. …

Micro- and millifluidic platforms for imaging agent synthesis
… To date the most widely used PET radiotracer is [18F]fluorodeoxyglucose ([18F]FDG). Despite the widespread use of [18F]FDG, 18F has a short half-life and [18F]FDG cannot detect certain cancers. There is a desire to develop radiometal-based radiotracers that have a wide selection of radioisotope …
