Objective To assess fractional anisotropy (FA) of sciatic nerve roots within the pelvis by using diffusion tensor imaging (DTI) in patients suffering from sciatica with inconclusive lumbar MRI. Methods This IRB-approved prospective study included 32 consecutive subjects (11 males and 21 females; mean age 32.2 years) between September 2019 and February 2020.
