We developed a semiautomatic technique to determine the arterial input function (AIF) in breath-hold DCE-MRI of the abdomen. The error in AIF was significantly reduced by tracking the motion of aorta. Also, we confirmed that the semiautomatic segmentation of the aortic region can reduce error in AIF induced by manual segmentation up to 15%.
