The purpose of the study is to evaluate and formalize a post-processing pipeline for DTI of the peripheral nerves using existing open source software suites. Our method integrates image registration, nerve segmentation, and DTI fiber tracking using the FMRIB software library (FSL) and MRtrix3, two popular software suites primarily used in the brain. 6 normal volunteers/patients and 9 nerves were analyzed and image quality was assessed. Using this protocol, image quality significantly improved in addition reducing processing time to 10 minutes using a semi-automated method.
