Mutual information between the FA and T1W images, with and without EPI distortion correction using the Synb0-DisCo technique. A: intraoperative MRI data acquired at the first surgical time point (iMRI₁), following cranial opening, prior to corticectomy and lesion resection. B: data acquired at the second surgical time point (iMRI₂) following initial lesion resection. The mutual information indices were significantly greater for EPI distortion corrected diffusion data compared to those without correction, at both surgical time points. * p < 0.001 ^** p < 0.0001. Abbreviation: intraoperative magnetic resonance imaging, iMRI; mutual information, MI. [print as a single image].
