Automated Determination of Arterial Input Function for Dynamic Susceptibility Contrast MRI from Regions around Arteries Using Independent Component Analysis

Various AIFs () are employed to test the deconvolution calculation for flow in dilution theory. “” (red line) is the ideal AIF defined in the paper [38] and the ideal flow is 80 mL/100 g⋅min. The thresholding value is the cut-off value in adaptive SVD calculation [33]. curves are the nonideal AIFs simulated.
