    摘要: A system and method for displaying MRI parameters measured from a tissue sample such a tumor. A computer system receives MRI data and determines a number of parameters including, a normalized cerebral blood volume (nCBV), a contrast transfer rate constant (kTrans) and apparent diffusion coefficient (ADC) calculated from Bo and B1000 MRI images for data points in the MRI data. These parameters are plotted onto a three-dimensional graph of voxels where the data in the MRI are mapped to a normalized radial distance and angle in the plot. The parameters nCBV, kTrans and 1/ADC are mapped to a color of the voxel and to height of a voxel in the +Z and −Z axes of the three dimensional plot.
