Positron emission tomography (PET) methods that use specific radioligands, other than FDG, are becoming available to evaluate patients with cancer. For example, choline [1] labeled with the positron emitter 11C (methyl-11C choline) has been introduced as a PET ligand to visualize various tumors, particularly those located in the pelvis, in which the background radioactivity of the tracer is low [2].

Abstract
Positron emission tomography (PET) methods that use specific radioligands, other than FDG, are becoming available to evaluate patients with cancer. For example, choline [1] labeled with the positron emitter 11C (methyl-11C choline) has been introduced as a PET ligand to visualize various tumors, particularly those located in the pelvis, in which the background radioactivity of the tracer is low [2]. We describe a patient who had undergone prostatectomy with a progressive increase of prostate-specific antigen (PSA) levels in whom PET with methyl-11C choline was determinant in indicating the presence of bone metastatic disease.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
