An ultra-high resolution, whole-brain DCE MRI with a temporal resolution of 1.5sec (3~4 times higher than conventional routine) and a spatial resolution of isotropic 1.0mm3 (5~6 times higher than conventional routine) is introduced in a real clinical setting to address problems related to arterial input function and partial volumes for precise estimation of vascular permeability information in brain cancer patients. Compared with conventional routine vendor-provided method, the proposed ultra-high resolution DCE MRI produces significant differences in permeability maps particularly for both Ktrans and ve.
