Brief Summary:
This study will examine the use of a variation of standard magnetic resonance imaging (MRI) called diffusion tensor MRI (DT-MRI), in order to evaluate the peripheral white matter infiltration of high grade brain tumors. Organized architecture is destroyed once brain tumor cells are infiltrating surrounding tissue. The infiltrated tissue is then isotropic (or less anisotropic). DT-MRI can assess anisotropy after datasets post treatment. Primary outcome is to find if a correlation exists between GA (generalized anisotropy) and the infiltration percentage of stereotactic peritumoral biopsies.

Condition or disease Intervention/treatment Phase
High Grade Brain Tumor Other: peritumoral glial cell infiltration Not Applicable

Detailed Description:

Patients with high grade brain tumor undergo a usual brain tumor MRI protocol as well as a 20 or 60 directions DT-MRI sequence upon patient collaboration. Images are acquired using a 3 Tesla MRI scanner (GE MR750 Discovery).

The usual brain tumor MRI protocol contains the following sequences: 3DT1, Axial T2, Flair, T2 EG, diffusion (b0-b1000), 3DT1CE.

They will then undergo stereotactic tumor biopsies with Leksell frame mounted.

Biopsy targets will be surgically planned. The coordinates of this first biopsy will be recorded for later coregistration with DT-MRI datasets.

Histopathologic analysis of the biopsies will be done using usual procedure. various immunologic markers such as MAP2, Ki67 will be used on the first biopsy sample in order to estimate the percentage of infiltration (ratio of tumor cells number over total cells number).

Analysis of DT-MRI datasets will be done using home-made software for high order tensor resolution and GA estimation at the exact coordinates of the biopsy sites.

Finally a statistical analysis (Pearson or Spearman) will be done to correlate GA and the infiltration percentage.
