ObjectiveThe objective of this work is to demonstrate the usefulness of high density diffusion tensor imaging techniques (HD-DTI 32 directions), to visualize the course of the cranial nerves prior to surgery in patients with skull base tumor disease. Materials and methodsTwenty-six patients with skull base tumor disease were studied with sequences of high density diffusion tensor imaging. The imaging results were correlated with the intra-operative findings. ResultsPre-surgical identification of the course of the nerves affected by the injuries of the skull base was possible in all the studied patients, with the imaging results correlating with the intraoperative findings. ConclusionThe visualization of the course of the cranial nerves with high density diffusion tensor imaging was shown to be safe and reproducible for the identification of cranial nerves and their course.
