Glucose metabolism has been shown to be increased in neoplastic tissue. It has been suggested that high activity of glucose metabolism is associated with a high grade of malignancy of human cancer. We studied in vivo glucose metabolism in 22 patients

[18F]Fluorodeoxyglucose (FDG) uptake in noncerebral tumors is commonly reported as tissue radioactivity concentration normalized to injected dose and body weight. We studied the feasibility of this approach by imaging 68 tumors in 46 oncologic patien

Quantitation of the uptake of positron emitting tracers in cancer patients is still unsettled. A uniform method is needed for comparison of results and for collecting a data base of tumor PET studies. We have measured the tumoral uptake of [11C]methi

L-[methyl-11-C]methionine (11C-methionine) uptake of seven primary breast cancers, four soft tissue metastases of breast cancer, and three other breast lesions was studied by positron emission tomography (PET). 11C-methionine accumulation was assesse

The aim of this study was to investigate whether uptake of carbon-11 methionine (MET) is associated with histological grade of malignancy and survival in patients with newly diagnosed or recurrent lymphoma. Thirty-two patients with histologically con
