Abstract：Objective To evaluate the diagnostic values of dif-ferent imaging examinations for giant cell tumor of long bone. Methods The imaging findings including X -ray,CT and MRI from 23 patients diagnosed as giant cell tumor of long bone were retrospectively analyzed.Results Circle or ellipse low -density areas,eccentric osteolytic expansile destruction of bone,soap bubble sign were found in 21 patients with X -ray and 1 7 patients with CT imaging respectively.There were eccentric growth, border sclerosis,soft tissue density in different degree and fluid -fluid levels in CT imaging findings,some lesions expanded to the joint surfaces.MRI of 7 patients showed normal long T1 WI /normal long T2WI,8 showed normal short T1 WI /normal long T2WI,1 showed normal T1 WI /normal long T2WI,2 showed long T1 WI /normal long T2WI.Slight high with mixed signals of STIR were found in 6 cases,high signals in other 8 cases.The relationship between fluid level ratio and benign or malignant tumors in 8 subjects with CT and MRI were different.Conclusion The combined usage of X -ray,CT and MRI could improve the diagnosis of giant cell tumor of limbs and the accuracy of differential diagnosis,which could provide an important basis for clinical treatment.The observation of fluid -fluid level in giant cell tumor in MRI was superior to CT.
