The aim of present article was to find and evaluate the diffusion weighted coefficients (b-values) for scrutinizing sciatic nerve tract changes in lumbosacral region. Materials and methods: Lumbar area was imaged in 30 patients with lower extremity pain in one side (left or right) at 1.5 T MR with routine protocols and DWI. Two stages for processing images were generated. Distance of sciatic nerve fibers between all patients In terms of Gray level average (GLA) and Contrast average (CA) on each side were calculated by MATLAB software. An appropriate statistical test such as Paired T test was used and. P M3 ER -
