Fig. 2From: Prospective comparison of early interim 18F-FDG-PET with 18F-FLT-PET for predicting treatment response and survival in metastatic breast cancerA case with metastatic breast cancer at the sternum. (A) 18F-FDG-PET, (B) 18F-FLT-PET. The lesion was clearly demarcated in 18F-FDG-PET. In 18F-FLT-PET, the margin of the lesion could not be well defined due to physiological 18F-FLT uptake in the adjacent bone marrowBack to article page
