I haven't devoted any time/effort/code to the extraction and parameter estimation of arterial input functions (AIFs) for DCE-MRI in either the vignette or the submission to JSS. Frankly, I wanted to communicate the main features of the R package dcemriS4 and data-driven AIFs just haven't made the list... up 'til now. So let's assume one wants to fit...
