PET images and time-activity curves. Left panels: Healthy Sprague-Dawley rats were intravenously injected with 68Ge/68Ga generator eluate. Images are summations from 0–180 min after injection and displayed in the same color scale as percentage of injected dose per gram of tissue (%ID/g). Male rat: 350 g, 50 MBq (0.007 MBq/kg); female rat 259 g, 48 MBq (0.005 MBq/kg). Right panels: Mean time-activity curves of 68Ga radioactivity in selected organs/tissues of male (upper) and female (lower) rats. Error bars denote standard deviation. According to Student’s t test, the differences in blood (P = 0.00026) and testes vs. uterus (P < 0.0001) were statistically significant at 180-min post-injection. The “blood” values were obtained from heart left ventricle
