[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
