Summary of the region-of-interest size and the difference in uptake between the two injection rates for the six patients

ROI A28387.049495.036137.87879.1
ROI B87.05084.02753.31983.5
  • Note.—Minimum, maximum, mean, and SD are for the region of interest (ROI) for all the examined patients.

  • * ROI A: Size (in mm2) with substantial pixel intensity (above background noise) summed for all brain sections for all patients. ROI B: Size (in mm2) with pixel intensity difference (either positive or negative) greater than 20% between the two injection rates. ROI C: The same results as in ROI B expressed as percentage of total area measured (ROI A).
