摘　　要：目的:探讨DTS在股骨头缺血坏死早期诊断中的应用价值。方法:将45例早期股骨头坏死病例作为研究对象,同期行DR、DTS及MRI检查,以MRI检查结果作为诊断股骨头缺血坏死的金标准,对DR、DTS检出率进行分析。结果:①X射线早期股骨头坏死检出率61.5%(40/65);DTS早期股骨头坏死检出率早期疾病检出率90.8%(59/65)。②DTS的早期ONFH检出率高于DR,差异有统计学意义(P<0.05)。结论:DTS在早期ONFH的检出率明显高于DR检出率,一些DR难以检出的早期病变,DTS可以检出,尤其发现早期骨质破坏的改变敏感度高,DTS对早期ONFH诊断具有重要价值,其价格实惠,患者易于接受,检查方便快捷,且禁忌症少,可为临床早期诊断、治疗及治疗后随访复查提供影像学依据。Objective:To explore the application value of DTS in early diagnosis of ONFH.Methods:Selected 45 patients underwented Magnetic Resonance Imaging(MRI),DTS,DR at the same day who were all confirmed early osteonecrosis of the femoral head(ONFH)with MRI.MRI was the gold standard on assessing ONFH.The detection rate of DR and DTS was analyzed.Result:①The DR detection rate of early ONFH is 61.5%(40/65),the DTS detection rate is90.8%(59/65).②The detection rate of DTS in the eaerly ONFH was higher than DR,and the difference was statistically significant(P<0.05).Conclusion:DTS detection rate of early ONFH was higher than DR,DTS could find early ONFH which DR couldn’t find,especially the early sensitivity of bone destruction is higher than DR,which has the important value to the early ONFH.It is cheaper,more convenient and less contraindications than MRI,it can be used for diagniosis of early osteonecrosis of the femoral head and providing the basis for the choice of clinical treatment.DTS can be used as an important means for early clinical diagnosis,and provide imaging for treatment and following up examinations.
