We
evaluated a feasibility of the usage of internal mammary artery near chest
wall as an artery input function in contrast enhanced dynamic MR study to
obtain the permeability map in breast tumor. Ktrans and Kep were successfully
measured using the internal mammary artery as an artery input function based
on the Tofts model in all patients. In breast tumor, the good performance in
fitting procedure and the acquired two parameters showed that the internal
mammary artery may be used as an artery input function in pharmacokinetic
analysis.
