  1. aThe TIAC of the kidneys were obtained by performing the time-activity curve fitting for both the left and right kidneys
  2. bThe TIAC values of urinary bladder contents were calculated using the voiding bladder model provided by OLINDA
  3. cThe TIACs for the remainder of the body were estimated by subtracting the organs’ TIACs from the whole-body TIACs
