This study evaluated the ability of 18F-FDG PET/CT imaging to predict early response to 90Y-radioembolization in comparison with contrast-enhanced CT (CECT) using RECIST and lesion density (Choi) criteria. Progression-free survival (PFS) in patients with liver metastases at 2 years and decline in tumour markers were the primary end-points of the study. A(More)
PURPOSE to investigate the role of FDG-PET and PET/CT in the evaluation of vasculitis. MATERIALS AND METHODS a systematic revision of the papers published in PubMed/Medline until December 2009 was done. RESULTS FDG-PET and PET/CT have been proven to be valuable in the diagnosis of large-vessel vasculitis, especially giant cells arteritis with(More)
UNLABELLED The aim of this study was to describe the normal physiological distribution of (68)Ga-DOTA-TATE using the SUV to reflect the density of somatostatin receptors in various organ systems. METHODS A total of 250 patients (90 men and 160 women) were imaged on a Biograph 64 PET/CT TruePoint (Siemens Medical Solutions) 60 to 80 minutes after injection(More)
The development of gallium-68 -1,4,7,10-tetraazacyclodecane-1,4,7,10-tetraacetic acid ((68)Ga-DOTA) compounds was made possible due to the chemistry of (68)Ga, which matches the pharmacokinetics of many peptides, specially the chelators DOTA and DOTAderivatives with the formation of stable (68)Ga (3+) complexes. The availability of this tracer from a(More)
INTRODUCTION Localization of ectopic parathyroid adenoma is highly important to guide surgery, thus reducing morbidity and rate of recurrent hyperparathyroidism. The aim of this study was to establish the incidence of ectopic parathyroid adenoma and evaluate the role of multimodality imaging in diagnosis. MATERIALS AND METHODS We reviewed 656 imaging(More)
Positron emission tomography (PET) has seen an increasing clinical utilization in the last decade, such that it is now a standard oncology imaging modality. Its success is based on the detection of altered fluorine-18 fluorodeoxyglucose (18F-FDG) biodistribution, reflecting glucose transport/metabolism in malignant tumor tissues. Integrated PET/computed(More)
The relatively new technique of positron emission tomography (PET) that incorporates both anatomy and function is increasingly being utilized in oncological imaging. This review assesses the use of PET of the liver for optimal and appropriate patient clinical management. The role of PET in both liver-lesion detection and characterization is discussed(More)
The EANM Congress 2011 took place in Birmingham between the 15th and 19th October 2011 under the presidency of Professor Werner Langsteger. The attendance was reassuringly high, in line with other EANM congresses, despite the current ‘Eurozone Crisis’. Participants from 87 countries came along, met old friends and made new ones. They were presented with a(More)
In 150 patients, 153 hepatic lesions (39 metastases, 27 hemangiomas, 26 hepatocellular carcinomas, 25 cysts, 15 adenomas, 8 focal nodular hyperplasias, 5 abscesses, 4 hamartomas, and 4 cholangiocarcinomas) were evaluated during a 24-month period. Apparent diffusion coefficient (ADC) values of benign lesions (1.994×10(-3) mm(2) s(-1)) were significantly(More)
