Spatial modulation of magnetization (SPAMM) technique can be used in the evaluation for any kind of continuous moving object including delicate flow of CSF in the spinal canal. In idiopathic spinal cord herniation, which results from dural defect of unknown origin, CSF flow is disturbed due to a focal anterior kink of spinal cord. SPAMM technique is helpful in showing a CSF flow separation due to herniated spinal cord. This characteristic CSF flow is distinguished from CSF flow of spinal arachnoid cyst.
