Case #1 (left) CT Perfusion reveals abnormal flow in a patient with liver mass. The plot displays the model fitted curve (cyan) compared to the measured data (yellow). The fitted arterial (red) and portal (blue) components are also displayed. Data courtesy of Drs Alex Pitman and Eddie Lau, Peter MacCallum Cancer Center.
Case #2 (right) Abnormal arterial and portal flow in a patient with liver mass (top row). Arterial flow reduction (bottom row) was detected at 1 month after drug therapy. Color arterial flow maps are overlaid on the corresponding CT image. Data courtesy of Dr Benjamin M. Yeh, MD, UCSF, USA.
