Figure 7. Role of intensity- and statistically-based parameters in ROI selection.

Figure 7

(A) Increasing ID levels were used to test the role of ID in ROI selection when ED=0 or 5 and STD=0 and %F=0 via SSMD analysis. (B) Increasing ID levels were used to test the role of ID in ROI selection when ED=0 or 5 and STD=22 and %F=35 via SSMD analysis. Statistically based parameters have a predominant role in selecting good quality ROI datasets as shown by SSMD>0.4 values. (C) Increasing %F values at different STD values were used to test the role of %F in ROI selection when ID=500 & ED=5 via SSMD analysis. (D) Increasing STD values at different %F values were used to test the role of STD in ROI selection when ID=500 & ED=5 via SSMD analysis. %F=22 & STD=35 are shown as the adequate values for good quality ROI selection, as shown by SSMD>0.4 values.
