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.
