title: Primary pelvic bone tumours in children and adolescents--imaging correlation.
abstract: Eight children aged 6 to 17 years (mean 13.3 years) were examined using conventional radiography, radionuclide bone scintigraphy, CT and MR imaging for pre-treatment assessment of extensive primary pelvic bone tumours. The tumours evaluated were Ewing's sarcoma (n = 4), osteogenic sarcoma (n = 3), and chondrosarcoma (n = 1). Each imaging modality made a contribution to the evaluation of the primary tumour. Conventional radiography and bone scintigraphy were necessary for the initial diagnosis, with CT playing a complementary role. MR imaging and/or dynamic contrast-enhanced CT were mandatory prior to surgical resection.
