Findings and procedure details
Osteosarcomas are malignant tumors of connective tissue producing osteoid matrix,
and varying amounts of fibrous tissue and cartilaginous matrix.
They are the most common primary bone tumors in children and adolescents and the second most common primary malignancy of bone,
after multiple myeloma.
Osteosarcomas are classified according to their degree of differentiation,
their location in the bone,
and histological type.

The various imaging modalities yield information that is essential for the planning of surgery on these lesions,
for the assessment of responses to medical management,
for identification of distant metastatic disease and local neoplastic relapse,
thereby give the treating physicians effective tools to enhance patient care.
