From: Quantifying Perfusion Properties with DCE-MRI Using a Dictionary Matching Approach
Dictionary Resolution Analysis. Six dictionaries were created with varying step sizes for AF as well as an additional six dictionaries with varying step sizes of MTT. A simulated contrast enhancement curve with known perfusion properties representing healthy liver tissue was matched against each dictionary. The resulting perfusion property values estimated using the dictionary matching method are plotted against the step size of that perfusion property used to generate the dictionary. The shaded overlays represent one standard deviation of the perfusion property values estimated at each step size. The black horizontal line in subfigure (a) represents the true AF value of 0.3. The black horizontal line in subfigure (b) represents the true MTT value of 15 s.
