(a) A post-contrast axial MR image from a head and neck cancer patient extracted from the DCE-MRI scan showing bilateral nodal metastases (dashed white lines) in the neck and the right carotid artery (solid red line). (b) An arterial input function (AIF) plot (plasma Gd-DTPA concentration time course). The data points were measured from the region of interest placed within the right carotid artery. The AIF wash-out phase was fitted with a bi-exponential decay function.
