MR Diffusion Tensor Imaging and Fiber Tracking in Spinal Cord Arteriovenous Malformations: A Preliminary Study

Abstract

We demonstrate that AVMs may interrupt, displace, or separate the fiber tracts and that clinical symptoms may be reflected by the quantitative FA results and the morphologic loss of fibers distant to the lesion. DTI with fiber tracking offers a novel approach to image spinal cord AVMs and may open a window to understand the complex pathophysiology of these lesions.
