X线、CT、MRI检查对骨巨细胞瘤临床价值比较

Comparison of diagnostic value of X ray,CT and MRI imaging in the diagnosis of giant cell tumor of bone

目的 比较X线、CT及MRI检查等影像学检查方法在骨巨细胞瘤中的临床诊断价值.方法收集骨巨细胞瘤（均经术后病理检查明确诊断）患者50例,对患者的X线、CT及MRI检查的影像学检查资料进行回顾性分析,并对骨巨细胞瘤的各项影像学检查特征进行总结探讨.结果 CT检查与MRI检查在骨质破坏上的诊断率高于X线检查诊断率差异无统计学意义（x2=4.181,P＞0.05）.CT检查与MRI检查在皂泡征、骨嵴、液-液平面及软组织肿块中的诊断率较X线检查高,差异均有统计学意义（x2=5.333、22.941、30.000、38.400、64.000、14.166、6.102、7.127,均P＆lt;0.05）.结论 CT检查与MRI检查在骨巨细胞瘤中的诊断准确率较X线检查更高,但其中MRI检查在肿瘤附近水肿情况上的诊断价值更优.

Objective To analyze the clinical value of X ray examination, CT examination and MRI examination in the diagnosis of giant cell tumor of bone.Methods 50 patients with giant cell tumor of bone confirmed by postoperative pathology were selected.The patients＇ X ray, CT scan and MRI imaging examination data were retrospectively analyzed, and the imaging features of giant cell tumor of bone were discussed and summarized.Results The rate of CT examination and MRI examination in the diagnosis of bone destruction was higher than X ray examination, but the difference was not statistically significant （x2=4.181,P〉0.05）.CT examination and MRI examination in the soap bubble sign, bone crest, liquid plane and soft tissue mass in the diagnostic rate compared with X ray examination was significantly higher, the difference was statistically significant （x2=5.333,22.941,30.000,38.400,64.000,14.166,6.102,all P〈0.05）.Conclusion The diagnostic accuracy of CT and MRI in giant cell tumor of bone is higher than X ray, but the value of MRI examination in the diagnosis of edema near the tumor is better.
