Overview
CT
- The role of CT scan in osteosarcoma is predominantly in assisting biopsy and staging, but 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:
- 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).
