We accessed a method for voxel-based partial volume correction for DCE-MRI. The spiral like trajectory of the complex blood signal was plotted in the complex plain and fitted by a logarithmic spiral to calculate the spiral center. The results demonstrate a strong correlation between echo time and accuracy of the analyzed data. Our results illustrate the limitations for using the method when applied to a 3D-GRE (DCE-MRI) sequence. The T2* 2D-GRE AIF analyzing method helps detecting and correcting partial volume artifacts which affect measurements of the arterial input function.
