Metastatic Adenocarcinoma Perfusion Maps. Representative liver perfusion maps from a patient with metastatic adenocarcinoma (subject 4) with three lesions visible on the shown slice as well as prototypical contrast agent enhancement curves. Maps of each of the three perfusion properties estimated from the dual-input single-compartment model (AF, DV, and MTT) are shown in the first three columns. Perfusion maps from curve fitting are shown in subfigures (a), (b), and (c). Perfusion maps from dictionary matching are shown in subfigures (e), (f), and (g). Subfigures (d) and (h) show the arterial and portal venous input functions for the patient as well as one representative contrast agent enhancement curve. Subfigure (d) depicts the estimated curve using curve fitting while subfigure (h) depicts the estimated curve using dictionary matching.
