We used a subjective expert educated approach to evaluate the potential value of DTI derived information. We considered a systematic neurosurgical expert review as usually performed on conventional MRI and in addition DTI derived imaging in patients with different etiologies of mass lesions. Both lesion characteristics and anatomical information on the main white mattter pathways were felt to be useful adjunct information not changing the principal decision to perform surgery but frequently altering considerations concerning surgical approach or extent of tumor resection or preoperative surgical risk assessments.
