The fundamental imaging features of osteosarcoma were showed bone destruction, periosteal reaction, neoplastic bone and soft-tissue mass. Among 49 cases examined by radiography, osteoblastic pattern sarcoma was found in 19 cases, osteolytic pattern sarcoma was found in 13 cases and mixed pattern sarcoma was found in 17 cases. The detection rates of bone destruction, periosteal reaction, soft-tissue mass, neoplastic bone and Codman triangle by radiography were respectively 61.2%, 95.9%, 71.4%, 73.5%and 27.7%. All 10 cases with CT scan were showed bone destruction, soft - tissue mass and neoplastic bone. The detection rates of periosteal reaction,憇ieve sign挶 and Codman triangle with CT scan were respectively 90%, 90% and 11%. The tiny neoplastic bone and"sieve sign"were showed sensitively by CT, but Codman triangle was showed by radiography superior to CT.32 cases with MRI scan presented the normal marrow was replaced by the tumor, which was showed low to intermediate signal intensity on T1-weighted images and promiscuity signal intensity on T2-weighted images. 7 cases presented hemorrhage and 24 cases presented necrosis.

骨肉瘤基本影像表现为骨质破坏、骨膜反应、瘤骨和软组织肿块。49例X线表现为成骨型19例，溶骨型13例，混合型17例；X线对骨质破坏、骨膜反应、软组织肿块、瘤骨和Codman三角的检出率分别为61.2%、95.9%、71.4%、73.5%和27.7%；10例CT表现均可见骨质破坏、软组织肿块及瘤骨，CT对骨膜反应、筛孔征和Codman三角的检出率为90%、90%和11%；CT对显示细小肿瘤骨和筛孔征最敏感，但对Codman三角的显示不如X线平片；32例MRI表现为骨髓腔内正常的骨髓高信号被肿瘤信号所取代，T1WI呈低～等信号，T2WI呈混杂信号，7例合并出血，24例中央坏死囊变，32例增强扫描均呈不均匀强化及瘤周可见水肿区。
