The aim of this study was to retrospectively evaluate the performance of positron emission tomography (PET) with 18F-fluorodeoxyglucose (18F-FDG) in children with lymphomas, at various stages of their disease. Twenty-eight children (mean age 12.5 years, 14 girls, 14 boys) with Hodgkin’s disease (HD, n=17) or non-Hodgkin’s lymphoma (NHL, n=11) were(More)
Positron emission tomography (PET) is now primarily used in oncological indication owing to the successful application of fluorine-18 fluorodeoxyglucose (FDG) in an increasing number of clinical indications at different stages of diagnosis, and for staging and follow-up. This review first considers the biological characteristics of FDG and then discusses(More)
PURPOSE Many anticancer therapies exert their therapeutic effect by inducing apoptosis in target tumors. We evaluated in a Phase I study the safety and the feasibility of (99m)Tc-Annexin V for imaging chemotherapy-induced apoptosis in human cancers immediately after the first course of chemotherapy. EXPERIMENTAL DESIGN Fifteen patients presenting with(More)
PRIMARY PURPOSE The staging of regional nodes by means of sentinel node detection has been shown to accurately detect subclinical nodal metastases from cutaneous melanoma. On the other hand, the oncological applications of 18F-fluoro-2-deoxy-D-glucose positron emission tomography (18FDG PET) are, nowadays, firmly established. However, the sensitivity of(More)
A new method is described for precise quantitative analysis of the relative three-dimensional distribution of myocardial tracers. The system uses a 360° elliptical sampling of radial slices to create activity profiles. These are then positioned onto a common centre at the same angular coordinates as the corresponding radial slice reconstruction planes to(More)
Despite advances in morphological imaging, some patients with lung cancer are found to have non resectable disease at surgery or die of recurrence within a year of surgery. At present, metastatic bone involvement is usually assessed using bone scintigraphy, which has a high sensitivity but a poor specificity. We have attempted to evaluate the utility of the(More)
Merkel cell carcinoma (MCC) is a rare and highly malignant skin cancer with neuroendocrine differentiation. We studied the potential value of 18FDG PET in the management of MCC. Eleven patients with MCC were examined by 18FDG PET and PET-CT for staging purpose (n=4) or for detection of recurrence (n=7). Qualitative and quantitative interpretation of PET(More)
OBJECTIVE The objective of this study was to assess the contribution of [(18)F]fluoro-2-deoxy-D-glucose positron emission tomography ((18)FDG PET) imaging in the management of cervical cancer. METHODS Fully corrected whole-body PET was performed in 60 patients (pts) with proven cervical cancer. In pretreatment staging, 22 pts underwent PET in addition to(More)
The aim of this study is the development of a database of normal women for quantitative analysis of exercise and reinjection myocardial single-photon emission computed tomography (SPET). We studied 101 subjects (40 males and 61 females) with less than 5% likelihood of coronary artery disease. All patients underwent stress and rest thallium-201 myocardial(More)
Positron emission tomography (PET) using fluorine-18 deoxyglucose (FDG), showing increased FDG uptake and retention in malignant cells, has been proven useful to differentiate malignant from benign tissue. We undertook a prospective study in 61 patients to compare the accuracy of whole-body FDG PET and conventional imaging (CI) methods for the staging of(More)
