Osteosarcoma CT

Introduction

Overview

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).
