Representative cases of FES/FDG group. Patients with 100% of the 18F-FES positive metastatic lesions were divided into two groups by the median ratio of FES/FDG SUVmax (0.96). (A) Low FES/FDG. A 59-year-old female patient with the range of 18F-FDG and 18F-FES SUVmax was 5.3–40.7 and 4.1–15.5, respectively. This patient’s median FES/FDG was 0.52, which was lower than the median FES/FDG of all patients. She has received fulvestrant treatment for 27.6 months until progress. (B) High FES/FDG. A 67-year-old female patient with the range of 18F-FDG and 18F-FES SUVmax was 3.0–8.1 and 8.8–16.0, respectively. This patient’s median FES/FDG was 2.32, which was higher than the median FES/FDG of all patients, and the PFS was 14.7 months.
