[Abstract] Currently, lumbar spinal stenosis is mainly diagnosed by imaging, espacially magnetic resonance imaging (MRI), which has become an important method due to its unique advantages. MRI shows the spinal canal stenosis with the transverse, sagittal and coronal surfaces intuitively. For the central spinal stenosis, some morphological manifestations of MR, such as nerve root sedimentation sign and redundant nerve roots can quantitatively or qualitatively determine the degree of spinal stenosis to help determine whether there are surgical indications. Diffusion tensor imaging based on the diffusion anisotropy of water molecules, makes a vector diagram or color coding to show the nerve fiber bundle imaging. By observing the nerve fiber bundle anomaly can quantitatively evaluate the degree of foraminal stenosis. Therefore, MRI has obvious advantages in diagnosis of lumbar spinal stenosis.
