A partial volume correction method for Dynamic Contrast-Enhanced MRI is presented that can correct for underestimation of first bolus passage in T1-weighted MRI. The method improves the robustness and precision of AIF measurement, even in very small ROIs, provided that the artery is oriented parallel to the main magnetic field.
