Osteogenic Sarcoma

 

 

Radiology

 

These investigations are used to determine the extent of disease prior to therapy.

Local Extent

Plain films
  • Permeative, destructive lesion.
  • Gold Standard

 

CT
  • Shows bone destruction well
  • Only useful in anatomically complex sites

 

MR
  • Shows intramedullary disease and soft tissue extension

 

Distant Extent

CT Chest

  • Pulmonary metastases

 

Bone Scan

  • Bone metastases

 

PET scan (if available)

  • Potential to show all sites of metastatic disease, but unproven

 

Patients are also followed with these studies to assess response to therapy and to rule out relapse once therapy is completed.
