ABSTRACT
Objective To analyze the CT features of osteosarcoma and chondrosarcoma and to explore the value of CT differential diagnosis.Methods The CT findings of 35 cases with osteosarcoma and 22 cases with chondrosarcoma confirmed by operation and pathology were analyzed retrospectively.P<0.05 for the difference was statistically significant.Results Periosteal reaction, Codman triangle, radial spicule, type Ⅰ and Ⅳ calcium-like density, long tubular soft tissue mass around greater than 1/2, the ratio of tumor CT to muscle CT (△T/△M) was statistically significant.Of all the above image performance, the sensitivity and specificity of the type I calcium-like density were the highest, while those of the type Ⅳ calcium-like density were the lowest.Conclusion The osteosarcoma is more likely to have the signs of periosteal reaction, Codman triangle, radial spicule and type Ⅰ calcium-like density, while the chondrosarcoma is more likely to have the signs of type Ⅳ calcium-like density.
