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.
CT
A CT scan of the primary osteosarcoma lesion helps delineate the location and extent of the tumor and is critical for surgical planning[1][2][3][4][5]:
- 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.
- 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).
