Neurosurgeons Use Novel MRI Diffusion Tensor Imaging Technique to Safely Remove Nerve Tumors

Traditional MRI scans are often unable to present a comprehensive view of each patient’s unique nerve fibers.

DTI uses the diffusion of water molecules in and around nerves to provide color 2-D or 3-D images of nerve fibers, and their relationship to schwannomas, a rare type of nerve tumor. The technique was developed by Northwestern Medicine (Chicago, IL, USA) neurosurgeon Michel Kliot, and functional neuroradiologist Thomas A. Gallagher.

Thomas A. Gallagher, said, "DTI can give us additional information about the organization of nerves as well as the diffusion properties within tumors; this is something that conventional MRI cannot do. Applications of this technology could extend beyond nerve tumors, and give us insight into many different nerve pathologies, traumatic nerve injuries and even the regrowth or recovery of nerves over time."
