PET (positron emission tomography) techniques and radiopharmaceutical tracers are becoming increasingly common in clinical practice. Since 1991, 3’-deoxy-3’-18Fluorine-Fluorothymidine (18F-FLT) has been studied as a PET tracer for tumor proliferation assessment. The purpose of this study was to assess tracer uptake (%ID/g) in tumor-bearing mice and the relationship between uptake values and Ki-67 expression. |
