Fig. 4From: The feasibility of [18F]EF5-PET/CT to image hypoxia in ovarian tumors: a clinical studyAn image of a patient with advanced ovarian cancer. All three metastases are FDG-avid (2b) and 2 of them have also accumulated EF5 (1b). The SUVmax-values in [18F]EF5-avid (tumor:gluteus maximus muscle ratio ≥ 1.5) are remarkably lower (1b) compared to the physiological uptake in bile (1.)Back to article page
