Automated Determination of Arterial Input Function for Dynamic Susceptibility Contrast MRI from Regions around Arteries Using Independent Component Analysis
Table 2
rCBFs are calculated by the AIFs determined by the manual ROI (Manu-roi) and ICA-based ROI (weighted-ICA) method in gray and white matter regions. The paired -test is employed to test the difference between the manual and ICA-based method in the artery ( and ) and surrounding tissue ( and ) and between the artery and surrounding tissue in the ICA-based method in gray and white matter regions.
