We apply a partial volume analysis to MR fingerprinting brain tumor data. In the analysis, the number and types of tissues that make up a given voxel are not assumed to be known a priori, which is particularly important in the case of abnormal tissues, such as tumors or edema. We examine the partial volume results in a patient with a glioblastoma multiforme (GBM) and another with a metastasis to look for patterns in healthy tissues, tumor, and the peritumoral region.
