ABSTRACT

MRI is extremely sensitive for detection of metastases in the vertebral bodies or in the epidural space. It can detect osseous metastases when findings on plain films are normal and when CT shows only subtle changes.
Metastases are generally of low signal intensity on T1 images showing the replacement of marrow fat by tumor and edema. MRI should be used for definition of the extent of the epidural and paravertebral lesion, quantification of the degree of cord, cauda equina compression and detection of multiple lesions.
