The dependence of SUV_MAX, blood-pool SUV_MEAN, cSUV_MAX, and the TBR on FDG circulating time-The average maximum carotid (A) and aortic (B). Arterial FDG activity was invariant to time, whereas blood-pool activity decreased and blood-pool corrected values and the target-to-background ratio significantly increased with time. Error bars represent the 95% confidence interval of the mean. ***P<.0001 decline or increase compared to previous time-point established by the paired Student’s t test (Reproduced with permission from Blomberg BA et al.)
