PURPOSE The purpose of this study is to give an overview of studies investigating the role of fludeoxyglucose F18 ((18)F-FDG) positron emission tomography (PET) scanning in patients with aortic aneurysms with a focus on molecular characteristics of the aneurysm wall. METHODS MEDLINE, EMBASE, and the Cochrane database were searched for relevant articles. After inclusion and exclusion, we selec...

Vascular prosthetic graft infection (VPGI) is a severe complication after vascular surgery. CT-scan is considered the diagnostic tool of choice in advanced VPGI. The incidence of a false-negative result using CT is relatively high, especially in the presence of low-grade infections. (18)F-fluorodeoxyglucose positron emission tomography ((18)F-FDG PET) scanning has been suggested as an alternati...

Patients suspected of recurrent differentiated thyroid cancer (DTC) may require "blind" (131)I therapy, with the disadvantage of unpredictable efficacy and toxicity. Alternatively, positron emission tomography (PET) with [(18)F]fluorodeoxyglucose ((18)FDG) can document the recurrence, thereby rationalizing therapeutic options. This study compared (18)FDG uptake in vivo with biomarkers expected ...

Background. The use of 2-[(18)F]fluoro-2-deoxy-D-glucose ([(18)F]FDG) may help to establish the antitumor activity of enzastaurin, a novel protein kinase C-beta II (PKC-betaII) inhibitor, in mouse xenografts. Methods. The hematologic cell line RAJI and the solid tumor cell line U87MG were each implanted in NOD/SCID mice. Standard tumor growth measurements and [(18)F]FDG PET imaging were perform...

UNLABELLED This study revisited (18)F-fluorodeoxyglucose ((18)F-FDG) uptake and its relationship to hypoxia in various tumor models. METHODS We generated peritoneal carcinomatosis and subcutaneous xenografts of colorectal cancer HT29, breast cancer MDA-MB-231, and non-small cell lung cancer A549 cell lines in nude mice. The partial oxygen pressure (pO2) of ascites fluid was measured. (18)F-FD...

UNLABELLED This study aimed to define the potential of 1-(11)C-acetate PET, compared with (18)F-FDG, in detecting meningiomas and monitoring the effect of gamma-knife radiosurgery. METHODS Twenty-two patients with the neuroradiologic diagnosis of meningioma were examined by 1-(11)C-acetate and (18)F-FDG PET on the same day. There were 12 cases of histopathologically proven meningioma (8 grade...

OBJECTIVES Clinical tumor imaging with (18)F-FDG in PET is growing in demand. This article will provide a review of current patient preparation and imaging techniques. The goal is to make the PET study as noninvasive as possible for the patient while obtaining quality images. Communication and coordination when scheduling these studies involves the patient and radiopharmacy, scanner, and suppor...

UNLABELLED Brain imaging with glucose ((18)F-FDG) PET or blood flow (hexamethylpropyleneamine oxime) SPECT is widely used for the differential diagnosis of dementia, though direct comparisons to clearly establish superiority of one method have not been undertaken. METHODS Subjects with Alzheimer disease (AD; n = 38) and dementia with Lewy bodies (DLB; n = 30) and controls (n = 30) underwent (...

UNLABELLED A 64-year-old male patient with small cell lung cancer underwent Fluorine-18 fluorodeoxyglucose (F 18 FDG) positron emission tomography (PET)/CT scan which revealed multiple F 18 FDG uptake in the spine, both humeri, ribs, pelvis and proximal long bones. There was no obvious lytic or sclerotic bone destruction accompanying these lesions on CT component of the study. After the patient...

UNLABELLED The purpose of this study was to estimate the fetal radiation exposure resulting from (18)F-FDG PET procedures performed in pregnant patients with malignancies. METHODS Five pregnant patients with a biopsy-proven diagnosis of malignancy who underwent (18)F-FDG PET studies were retrospectively reviewed. All patients underwent PET-only studies (and not PET/CT studies) with a reduced ...
