Abstract:
Objective： The current study was designed to assess the value of radiography on surgical margins of osteosarcoma. Methods： Tumor extension showed on X-ray plane film, CT and MRI was measured in 29 patients, and these data were analyzed statistically associated with pathological examination. Result： The width of tumor on X-ray plane film, CT and MRI was 42.7± 17.7 mm,70.1± 22.7 mm,73.3± 27.7 mm, respectively, and the length was 71.6± 24.5 mm,84.4± 30.3 mm, 123.6± 36.5 mm, respectively. As the result of histologic examination, the width of the tumor was 72.9± 26.1 mm, and the length was 119.8± 34.8 mm. The aggressive extension on MRI was similar to that on histologic exmination, and were more accurate than that on X-ray film and CT. Conclusion： It was reliable that the surgical margins were estimated on MRI.
