UNLABELLED In patients with inflammatory bowel disease (IBD) and in murine IBD models, mucosal disease activity is routinely assessed by endoscopy and histologic evaluation. This information is valuable for monitoring treatment response, with mucosal healing being a major treatment goal. The aim of this study was to evaluate the translational potential of noninvasive (18)F-FDG PET/CT for the as...

UNLABELLED The aim of this study was to evaluate the potential role of positron emission tomography (PET) with 18F-fluorodeoxyglucose (FDG) in patients with unexplained rising serum alpha-fetoprotein (AFP) levels after the treatment of hepatocellular carcinoma (HCC). PATIENTS AND METHODS Thirty-one FDG-PET studies were performed in 26 patients (age range, 45-83; 21 men and 5 women), who had u...

Abstract Purpose While radiotherapy (RT) for head and neck cancer (HNC) has made recent strides, RT-induced vasculitis continues to adversely affect long-term patient outcomes. Guidelines managing this complication remain scarce, supporting the need a sensitive imaging modality in post-treatment evaluations. In review, we discuss current literature regarding 18 F-fluorodeoxyglucose positron emi...

AIMS FDG-PET can be used to identify vulnerable plaques in atherosclerotic disease. Clinical FDG-PET camera systems are restricted in terms of resolution for the visualization of detailed inflammation patterns in smaller vascular structures. The aim of the study is to evaluate the possible added value of a high-resolution microPET system in excised carotid plaques using FDG. METHODS AND RESUL...

We synthesized a novel, multi-functional, radiosensitizing agent by covalently linking 6-fluoro-6-deoxy-D-glucose (6-FDG) to gold nanoparticles (6-FDG-GNPs) via a thiol functional group. We then assessed the bio-distribution and pharmacokinetic properties of 6-FDG-GNPs in vivo using a murine model. At 2 h, following intravenous injection of 6-FDG-GNPs into the murine model, approximately 30% of...

OBJECTIVE Pulmonary metastasectomy is beneficial in select patients. The sensitivity of (18)F-fluorodeoxyglucose positron emission tomography (FDG-PET) for pulmonary metastasis is unknown. The aims of the study were to determine the accuracy of FDG-PET in detecting pulmonary metastasis and identify factors affecting sensitivity. METHODS All patients undergoing metastasectomy from September 20...

Perfluorocarbon (PFC) double emulsions loaded with a water-soluble, therapeutic agent can be triggered by ultrasound in a process known as acoustic droplet vaporization. Elucidating the stability and biodistribution of these sonosensitive vehicles and encapsulated agents is critical in developing targeted drug delivery strategies using ultrasound. [(18) F]fluorodeoxyglucose (FDG) was encapsulat...

UNLABELLED Tumors often have an increased uptake of glucose and can be detected by PET imaging using 18F-FDG. 18F-FDG is converted to 18F-FDG-6-phosphate (18F-FDG-6-P), and the usual assumption is that 18F-FDG-6-P is not a substrate for subsequent enzymatic reactions and that tumor hot spots reflect trapping of 18F-FDG-6-P. We recently found, however, that in the pig liver, 18F-FDG is metaboliz...

OBJECTIVES Although diffuse splenic (18)F-fluorodeoxyglucose (F-18 FDG) uptake exceeding hepatic activity, is considered abnormal, its clinical significance is rarely discussed in the literature. The aim of this study was to determine the contributing factors causing diffusely increased splenic FDG uptake in patients with cholangiocarcinoma. METHODS From January 2010 to March 2013, 140 patien...

UNLABELLED Our objective was to compare the diagnostic accuracy of an all-in-one protocol of whole-body 18F-FDG PET/CT and integrated 18F-FDG PET/CT mammography with the diagnostic accuracy of a multimodality algorithm for initial breast cancer staging. METHODS Forty women (mean age, 58.3 y; range, 30.8-78.4 y; SD, 12 y) with suspected breast cancer were included. For the primary tumor, we co...
