The authors examined 27 cases of bone tumor patients with CT and reported the value of CT diagnosis and indications. Twenty-two malignant tumors in 27 cases (15 bones and 7 soft tissues): 9 Ewing's sarcoma, 3 bone sarcoma, 2 rhabdomyosarcoma, 1 fibrosarcoma, 1 vascular sarcoma, 1 neuroblastoma. There were 3 cases of metastases, 2 cases of synovial sarcoma, and 5 cases of benign tumors. Nine typical cases, such as a flat piece of Ewing's sarcoma of the humerus that is difficult to see, CT shows the destruction of the sacrum and presacral mass; a case of Ewing's sarcoma of the femur shows a clear boundary between normal bone and the tumor. Radioisotopes in tablets and bones are examined more clearly and the surgery is approved
