Abstract:
Objective To evaluate the maturity and metabolic status of heterotopic ossification(HO)by single-photon emission computed tomography(SPECT)/CT fusion bone imaging.Methods The clinical and SPECT/CT fusion bone imaging data of 57 patients with HO confirmed by pathology or follow-up were analyzed retrospectively.HO was graded by CT,and the characteristics of radioactive concentration of HO were analyzed.Results Of 57 cases,single lesion in 52 cases,and multiple lesions in 5 cases,with a total of 63 lesions,mostly located in the hip joint(55.6%,35/63)and thigh(19.0%,12/63).There were 41 lesions in the middle stage and 22 lesions in the late stage.In the visual evaluation of SPECT/CT fusion bone imaging,the middle stage lesions were mostly clumps or flakes,with moderate or high radioactive concentration(75.6%,31/41),furthermore,the concentration range was larger than or equal to the total or limited range of CT ossification(21/41,50.1%),with high concentration mainly located in the mixed areas of ossification density.The concentration of the late stage lesions was mostly non-radioactive(72.7%,16/22).Conclusion SPECT/CT fusion bone imaging can show the range,degree and maturity of HO radioactive concentration,and can accurately locate the area with osteoblastic activity,which provides scientific basis for the selection of surgical timing.
