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.
• 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).
