IntroductionPreclinical Goals
• Goal 1: Develop a molecular and imaging based classification for genetically engineered mouse models (GEMs) of glioblastoma multiforme (GBM)
• Goal 2: Use imaging to asses response of GBM GEMs to novel therapeutic regimens

Mouse GBM Pilot Collection Purpose
• Utilize NBIA and caIntegrator to correlate image-based features with ‘clinical’ data in GBM mouse models• Image-based features
• Qualitative• Quantitative blood brain barrier permeability
• ‘Clinical’ features• Genotype• Tumor histologic characteristics• IHC— e.g., CD31
• One time imaging in n=62 mouse patients

Mouse GBM Pilot Collection Animal models
• Intracranial injection of cell lines derived from several GEMs
• Genotypes:• Rb inactivation + Ras activation • Rb inactivation + Ras activation + PTEN loss • Rb inactivation + Ras activation + EGFR loss
