Spinal Cord Imaging

Hi,
I am a PhD student from University of Genoa, Italy, and I attended the MRtrix workshop in Antwerp in September. I am writing to you since I am currently working on spinal cord images of pediatric patients and I need to analyse them with DKI. Images seem to be quite noisy. I would like to know whether any MRtrix algorithm exist in order to enhance these images or if you know about any other toolbox. Any suggestion is useful!
Thank you,
Rosella ![Screenshot%20from%202019-10-24%2011-29-05|690x338](upload://f1H8wVTN0EbImaFtUbV1vTj3LCw.jpeg)
