Syringomyelia

Surgical skill and imaging technology in the field of neurosurgery have developed remarkably during the past decade. Magnetic resonance imaging (MRI), with high­ contrast resolution and multiplanar capabilities, allows for accurate preoperative localization and postoperative assessment of syringomyelia. Recent advances in dynamic MRI techniques have made it possible to evaluate normal and abnormal cerebrospinal fluid (CSF) flow at the foramen magnum, within the syrinx, and in the spinal subarach
