MR imaging of intradural tumors of the cervical spine.

MR imaging is the modality of choice for intradural spinal tumors because of its unsurpassed depiction of soft tissues, the use of intravenous contrast, the absence of beam-hardening artifacts, and the ability to image in multiple planes. Intradural tumors are classified as intradural-extramedullary and intradural-intramedullary. MR imaging techniques that best depict these tumors are reviewed, and several examples of tumors are described and illustrated.
