Glioblastoma demonstrates imaging features of intratumor heterogeneity that result from underlying heterogeneous biological properties. This stems from variations in cellular behavior that result from genetic mutations that either drive, or are driven by, heterogeneous microenvironment conditions. Amongst all imaging methods available, only T1-weighted contrast-enhancing and T2-weighted fluid attenuated inversion recovery are used in standard clinical GBM assessment and monitoring. Advanced imaging modalities are still considered emerging techniques as appropriate endpoints and robust methodologies are missing from clinical trials. Discovering how these images specifically relate to the underlying tumor biology may aid in improving quality of clinical trials and understanding the factors involved in regional responses to treatment, including variable drug uptake and effect of radiotherapy. Upon validation and standardization of emerging MR techniques, providing information based on the underlying tumor biology, these images may allow for clinical decision-making that is tailored to an individual’s response to treatment.
