%diff and |%diff| in 18F-FDG Uptake (kBq/mL) Between CT-AC and Each s-/m-Atlas in All Regions (67 × 15 = 1,005 VOIs)

ParameterWith TOFWithout TOF
%diff on s-Atlas*0.17% ± 1.82%0.06% ± 2.13%
%diff on m-Atlas*−0.06% ± 1.50%0.03% ± 1.92%
|%diff| on s-Atlas†1.49% ± 1.06%1.71% ± 1.28%
|%diff| on m-Atlas†1.21% ± 0.89%1.51% ± 1.19%

  • ↵* s-Atlas vs. m-Atlas, P < 0.01.

  • ↵† With TOF vs. without TOF, P < 0.01.

  • %diff is CT-AC minus s-/m-AC, divided by CT-AC. |%diff| is absolute value of %diff.
