We visualizedsciatic and femoral nerves andcompared the fractional anisotropy (FA) values of the sciatic and femoral nerves in patients with osteoarthritis of the hip (OA) and osteonecrosis of the femoral head (ONFH) using diffusion tensor imaging (DTI). This study indicates thatthe FA values for the sciatic and femoral nerves in patients with OA and ONFH showed no significant differences with normal hips indicating no degeneration or demyelination occurred in either nerve. DTI may be able to differentiate hip diseases from lumbar nerve radiculopathy.
