Positron emission tomography (PET) is now regularly used in the diagnosis and staging of cancer. These uses and its ability to monitor treatment response would be aided by the development of imaging agents that can be used to measure tissue and tumor proliferation. We have developed and tested [F-18]FLT (3'-deoxy-3'-fluorothymidine); it is resistant to(More)
The aim of this study was to evaluate the use of 124I positron emission tomography (PET) to determine the dosimetry of radioiodine therapy in hyperthyroidism and thyroid cancer. Phantom studies to assess the accuracy of PET were performed using an EEC phantom with spheres of different diameters filled with 3–30 MBq of 124I. Patient dosimetry was derived(More)
This study evaluated the use of 3′-deoxy-3′-[18F]fluorothymidine ([18F]FLT) for monitoring of the early effects of anticancer chemotherapy on tumour cell proliferation. Cells derived from human oesophageal squamous cell carcinoma (OSC-1) were grown for 2 days and incubated with cisplatin (CDDP), 5-fluorouracil (5-FU), methotrexate (MTX) or gemcitabine (GEM)(More)
AIM In advanced seminoma the management of residuals after completion of chemotherapy is controversial. Some centres routinely perform surgery for lesions > or =3 cm diameter, others recommend surgery solely if the residual fail to shrink or show even growth. This study prospectively investigates whether FDG PET can improve the prediction of viable tumour(More)
PURPOSE To establish the predictive potential of 2-18fluoro-2-deoxy-D-glucose positron emission tomography (FDG PET) for detecting viable tumor tissue in residual postchemotherapy masses of seminoma patients. PATIENTS AND METHODS In this prospective multicenter trial, results of FDG PET studies in seminoma patients with postchemotherapy masses > or = 1 cm(More)
Dear Sirs, Recently, faciobrachial dystonic seizures (FBDS) have been described as an indicative seizure type in encephalitis due to antibodies against leucine-rich glioma inactivated-1 (LGI1), a component of the voltage-gated potassium channel (VGKC)-complex [3]. The authors of the index study suggested these to be epileptic seizures. Others have argued(More)
BACKGROUND The pleasant effects of food and alcohol intake are partially mediated by mu-opiate receptors in the ventral striatum, a central area of the brain reward system. Blockade of mu-opiate receptors with naltrexone reduces the relapse risk among some but not all alcoholic individuals. OBJECTIVE To test the hypothesis that alcohol craving is(More)
The aim of this study was to evaluate fluorine-18 fluorodeoxyglucose positron emission tomography ([18F]FDG PET) as a tool for the differential diagnosis of pancreatic carcinoma while taking into account serum glucose level. A group of 106 patients with unclear pancreatic masses were recruited for the study. PET was performed following intravenous(More)
PURPOSE To define the clinical value of 2-18fluoro-deoxy-D-glucose positron emission tomography (FDG PET) as a predictor for viable residual tumor in postchemotherapy seminoma residuals in a prospective multicentric trial. PATIENTS AND METHODS FDG PET studies in patients with metastatic pure seminoma who had radiographically defined postchemotherapy(More)
The nucleoside analogue 3'-deoxy-3'-[18F]fluorothymidine (FLT) has been introduced for imaging of tumour cell proliferation by positron emission tomography (PET). This study evaluated the use of FLT in patients with thoracic tumours prior to treatment. Whole-body FLT PET was performed in 16 patients with 18 tumours [17 thoracic tumours (nine non-small cell(More)
