Official Title: Differentiation of Pseudoprogression and True Progression Through High Field Susceptibility Weighted Imaging and R2*
Brief Summary: Using a multi-echo gradient echo sequence to calculate R2* and quantitative susceptibility maps and well as susceptibility-weighted imaging post processing the investigators hypothesize that the investigators would be able to distinguish between pseudoprogression and true progression with the use of an easily implementable sequence on clinical MRI scanners.
