Summary

VASARI currently consists of image data from Thomas Jefferson University (TJU) and Henry Ford, as well as some annotations performed by 3 of TJU's radiologists while reviewing the TJU images. This 130 case MR multi-sequence image collection of pre-surgical brain tumor patients can be matched by each unique case identifier with the extensive gene and expression data of the same case available from the REMBRANDT Data Portal to research the link between radiological phenotype and tissue genotype. This genetically profiled MRI collection contains numerous cases of glioblastoma, astrocytomas and oligodendrogliomas.
