Comparison of diagnostic value of X ray,CT and MRI imaging in the diagnosis of giant cell tumor of bone / 中国基层医药

ABSTRACT

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.
