【摘要】：目的探討多普勒超聲診斷中軸型脊柱關(guān)節(jié)病(axSpA)患者活動(dòng)性骶髂關(guān)節(jié)炎的價(jià)值。方法回顧性分析51例早期axSpA患者的多普勒超聲及MRI資料。依據(jù)MRI結(jié)果將axSpA患者分為活動(dòng)性骶髂關(guān)節(jié)炎(活動(dòng))組及非活動(dòng)性骶髂關(guān)節(jié)炎(非活動(dòng))組,比較2組骶髂關(guān)節(jié)的血流顯示情況及血流阻力指數(shù)(RI)。以MRI結(jié)果為金標(biāo)準(zhǔn),繪制ROC曲線,評(píng)價(jià)RI對(duì)axSpA患者活動(dòng)性骶髂關(guān)節(jié)炎的診斷效能。結(jié)果活動(dòng)組32例共58個(gè)病變關(guān)節(jié)(6例為單發(fā)活動(dòng)性骶髂關(guān)節(jié)炎),非活動(dòng)組19例共38個(gè)病變關(guān)節(jié)。活動(dòng)組骶髂關(guān)節(jié)血流顯示率(51/58,87.93%)高于非活動(dòng)組(26/38,68.42%;χ~2=5.505,P=0.019)。2組間血流分級(jí)差異無統(tǒng)計(jì)學(xué)意義(Z=-1.93,P=0.053)�；顒�(dòng)組RI值(0.59±0.08)低于非活動(dòng)組(0.71±0.09;t=-6.04,P0.001)。以RI=0.64診斷axSpA患者活動(dòng)性骶髂關(guān)節(jié)炎,敏感度為80.8%,特異度為74.5%,準(zhǔn)確率為78.7%。結(jié)論利用多普勒超聲可通過骶髂關(guān)節(jié)周圍及內(nèi)部的異常血流來反映axSpA患者活動(dòng)性骶髂關(guān)節(jié)炎,且準(zhǔn)確率較高。
[Abstract]:Objective to evaluate the value of Doppler ultrasonography in the diagnosis of active sacroiliac arthritis in patients with axial spondyloarthropathy (axspa). Methods the Doppler ultrasound and MRI findings of 51 patients with early axspa were retrospectively analyzed. Patients with axspa were divided into active sacroiliac arthritis (active) group and inactive sacroiliac arthritis (inactive) group according to MRI results. The blood flow display and blood flow resistance index (RI) of sacroiliac joint were compared between the two groups. Using MRI results as gold standard, the ROC curve was drawn to evaluate the diagnostic efficacy of RI for active sacroiliac arthritis in patients with axspa. Results there were 58 diseased joints (6 cases of single active sacroiliac arthritis) in active group and 38 cases in inactive group (19 cases). The blood flow display rate of sacroiliac joint in the active group (51 / 58) was higher than that in the inactive group (26 / 38) (68.42). The RI of the active group (0.59 鹵0.08) was lower than that of the inactive group (0.71 鹵0.09). The sensitivity, specificity and accuracy of the diagnosis of active sacroiliac arthritis in patients with axspa were 80.8, 74.5 and 78.7 respectively. Conclusion the abnormal blood flow around and inside the sacroiliac joint can be used to reflect the active sacroiliac arthritis in patients with axspa by Doppler ultrasound, and the accuracy is high.
