Model calculation of quantification input parameters effect on CBF calculation.

Parameters mean GM CBF (mL/100 g/min) mean WM CBF (mL/100 g/min)
Real parameters:
PLD: 2,025 ms, LD: 1,450 ms,
blood T1: 1,650 ms, PVC		 53.3 21.7
Falsely reduced PLD:
PLD: 1,800 ms, LD: 1,450 ms,
blood T1: 1,650 ms, PVC		 46.5 18.9
Falsely reduced LD:
PLD: 2,025 ms, LD: 1,200 ms,
blood T1: 1,650 ms, PVC		 60.3 24.5
Falsely reduced blood T1:
PLD: 2,025 ms, LD: 1,450 ms,
blood T1: 1,450 ms, PVC		 66.4 27.0
Without PVC:
PLD: 2,025 ms, LD: 1,450 ms,
blood T1: 1,650 ms, no PVC 		40.3 21.3

Starting from the correct quantification, GUI parameters input in row 1, PLD, LD, blood T1, and omission of PVC were subsequently used incorrectly to demonstrate their effects of each modulation. PLD, post-labeling delay; LD, labeling duration; blood T1, T1 relaxation of blood; PVC, partial volume correction.
