title: Early detection of bone metastases of Ewing's sarcoma by magnetic resonance imaging.
abstract: Bone metastases of an Ewing's sarcoma were detected by magnetic resonance imaging (MRI), when bone scan, CT and plain films were still normal. This is due to the ability of MRI to detect intramedullary metastases before involvement of the cortex.
