UNLABELLED We studied the metabolic characteristics of RCC subtypes and angiomyolipoma with 18F-FDG and 11C-acetate PET/CT. METHODS Fifty-eight patients with both baseline CT and dual-tracer PET/CT were recruited: 10 angiomyolipoma (16 lesions) and 48 RCC (50 lesions). Each lesion was assessed for SUVmax ratio (lesion-to-normal kidney) on(More)
A simple, efficient and remotely operated synthesis apparatus for carrying out routine [(11)C]carboxylation, on-column and bubbling [(11)C]methylation was essential for reliable, day-to-day production of [(11)C]-labelled PET radiopharmaceuticals. We developed an in-house apparatus specifically applied to the synthesis of [(11)C]acetate, [(11)C]choline,(More)
[11C]Acetate (ACT) positron emission tomography/computed tomography (PET/CT) is useful in the detection of hepatocellular carcinoma (HCC). This study aimed to evaluate whether [18F]fluoroacetate (FAC) could be an alternative analogue of [11C]ACT for the diagnosis of HCC. [18F]FAC was synthesized using the precursor t-butyl 2-(methanesulfonyloxy)ethanoate.(More)
