title: [Digital angiography of bone sarcoma in the child].
abstract: The authors analyze the results of 50 computed angiographies made for osteosarcoma and Ewing's sarcoma. Better tolerated than conventional angiography computed angiography is also more sensitive in preoperative evaluation of effectiveness of neoadjuvant chemotherapy. Automatic subtraction, direct measuring of tumor size and vascularization density give to angiographic changes after chemotherapy the most predictive value. After conservative surgery or radiotherapy digital angiography provides most reliable local follow up.
