4 the proliferation of bone can be seen in sarcoma, hemangioma and meningioma.
Myelography for positioning the spinal cord or cauda equina compression level, contrast agent completely or nearly completely obstruction, intradural extramedullary tumor often cupping the obstruction, intramedullary tumor showed enlargement of the spinal column profile, contrast agent were pushed to the side.
CT and CTM: the examination of the nervous system can correctly provide the lesion of CT, spinal cord, spinal cord tumor can accurately display, easy to clear the destruction of vertebrae.
MRI: the majority of spinal cord tumors, including T1 weighted images of metastatic tumors are reduced or unchanged. T2 weighted images showed signal enhancement, but in the case of neuroblastoma, some of the advanced pancreatic cancer bone metastases were reduced. One
