Abstract B-cell lymphoblastic lymphoma (B-LBL) is an uncommon subtype of pediatric non-Hodgkin Lymphoma (NHL) which rarely involves the skin primarily. The positron emission tomography with 2-deoxy-2-[fluorine- 18] fluoro-D: -glucose integrated with computed tomography (18F-FDG PET/CT) scan findings of a 8-year-old boy with cutaneous B-LBL were presented. PET/CT scan demonstrated mild FDG up...

UNLABELLED Uptake of 18F-fluorodeoxyglucose (FDG) and 11C-methionine (Met) in mediastinum and hilar lymph nodes was studied using PET in 31 patients with sarcoidosis. The aim of our study was to examine whether these different tracers play a differential role in clinical assessment of pulmonary involvement. METHODS Fluorine-18-fluorodeoxyglucose and 11C-Met PET were administered on different ...

The aim of the study was to compare differences between lymphoma and inflammation as indicated by high diffuse uptake of F-fluorodeoxyglucose (F-FDG) in the spleen, liver, and bone marrow without increased F-FDG uptake in the lymph nodes and without enlarged peripheral lymph nodes.Eighteen lymphoma patients and 14 inflammation patients were examined with F-FDG positron emission tomography-compu...

UNLABELLED The aim of this prospective study was to investigate if high uptake of 18F-fluoro-2-deoxy-D-glucose (FDG) is associated with aggressiveness in head and neck cancer and low probability of survival. METHODS Thirty-seven patients with squamous-cell carcinoma of the head and neck underwent FDG-PET in the fasting state before cancer treatment. FDG uptake in primary tumor was quantitated...

18F-FDG PET is emerging as a useful tool in the staging and restaging of many malignant neoplasms, such as lymphoma, lung cancer, colorectal cancer, head and neck cancer, breast cancer, and melanoma. To accurately interpret 18F-FDG findings one must be familiar with the normal physiologic distribution of the tracer, frequently encountered physiologic variants, and benign pathologic causes of 18...

UNLABELLED Small-animal PET scanning with (18)F-FDG is increasingly used in murine models of human diseases. However, the impact of dietary conditions, mode of anesthesia, and ambient temperature on the biodistribution of (18)F-FDG in mice has not been systematically studied so far. The aim of this study was to determine how these factors affect assessment of tumor glucose use by (18)F-FDG PET ...

UNLABELLED Increased myocardial uptake of 18F-fluorodeoxyglucose (FDG) in regions with perfusion defects (perfusion-FDG mismatch) has been shown to predict functional recovery after revascularization; conversely, a concordant decrease in perfusion and FDG uptake (perfusion-FDG match) represents scar tissue (varying from subendocardial to transmural scar) that will not improve in contractile fun...

BACKGROUND Increased somatostatin receptor (SSTR) expression in patients with undifferentiated nasopharyngeal carcinoma (NPC) has been demonstrated with receptor autoradiography, (111) In-Octreotide scintigraphy, and (68) Ga-DOTA-TOC positron emission tomography (PET)/CT imaging. We sought to compare and correlate the uptake of fluorodeoxyglucose (FDG) and DOTA-NOC in undifferentiated NPC to as...

Thyroid nodules that exhibit focal uptake of fluorine-18 ((18)F)-fluorodeoxyglucose (FDG) are relatively frequent. Although the clinical features and associated mechanisms of FDG-avid lesions in both thyroid cancer and cytologically indeterminate nodules have been extensively studied, not much information is available on benign nodules. Therefore, in this retrospective study, the clinical, sero...

AIM To study whether (18)F-FDG can be used for in vivo imaging of atherogenesis by examining the correlation between (18)F-FDG uptake and gene expression of key molecular markers of atherosclerosis in apoE(-/-) mice. METHODS Nine groups of apoE(-/-) mice were given normal chow or high-fat diet. At different time-points, (18)F-FDG PET/contrast-enhanced CT scans were performed on dedicated anim...
