Overview

CT scan in osteosarcoma may be helpful in biopsy and staging. CT scan adds little to plain radiography and MRI in direct assessment of the tumor.[1]

CT

  • CT scan in osteosarcoma may be helpful in biopsy and staging.
  • CT scan adds little to plain radiography and MRI in direct assessment of the tumor.[1]
  • The exception to this rule is predominantly lytic lesions in which small amounts of mineralised material may be inapparent on both plain film and MRI.
  • CT scan is used to:[2]
  • Observe the extent of the bone tumor.
  • Observe if the tumor has spread into nearby tissues.
  • Guide a biopsy needle to the tumor (CT-guided biopsy).
  • Observe if the bone cancer has spread to the lung (metastasis).
