Intra operative MRI with Diffusion Tensor Imaging allows identification of white mater tracks during surgery allowing for a more aggressive approach by the surgeon while preserving eloquent structures. However DTI is prone to artefacts from B0 inhomogeneity. In this abstract we present our initial experiences on the effect of a commercially available Echo Planar Imaging Correction in the intraoperative setting. While overall image quality is increased, further studies on a larger number of patients are required before the clinical effect can be assessed.
