【摘要】：目的應(yīng)用三維超聲水平中心線法聯(lián)合骨骼模式成像定位胎兒脊髓圓錐位置,探索脊髓圓錐位置隨孕周的變化規(guī)律。方法選取420例正常胎兒,應(yīng)用三維超聲水平中心線法聯(lián)合骨骼模式成像定位胎兒脊髓圓錐位置,分析胎兒脊髓圓錐對應(yīng)椎體水平與孕周的相關(guān)關(guān)系;應(yīng)用t檢驗進行耗時差異分析;應(yīng)用Kappa檢驗進行可重復(fù)性分析。結(jié)果 (1)胎兒脊髓圓錐三維超聲顯示率為97.6%。(2)胎兒脊髓圓錐與孕周之間的線性回歸方程為:Y=-6.446X+41.547(R=0.771,R2=0.594,P0.001)。(3)二維超聲組較三維超聲組耗時平均多30s,95%可信區(qū)間0.96~0.82(P0.001)。(4)二維與三維超聲兩種方式定位胎兒脊髓圓錐位置以及操作者間、操作者內(nèi)定位胎兒脊髓圓錐一致性檢驗加權(quán)Kappa值分別為0.96、0.92、0.95。結(jié)論三維超聲水平中心線法聯(lián)合骨骼模式成像能夠準確定位胎兒脊髓圓錐位置。
[Abstract]:Objective to locate the position of fetal spinal cord cones by three-dimensional ultrasound horizontal centerline combined with skeletal mode imaging, and to explore the changes of the position of spinal cord cones with gestational weeks. Methods 420 normal fetuses were selected. The position of fetal spinal cord cones was located by three-dimensional ultrasound horizontal centerline combined with skeletal mode imaging, and the correlation between fetal spinal cord cones and gestational weeks was analyzed. T test was used to analyze the difference of time consuming; Reproducibility analysis was performed by Kappa test. Results 1) Three-dimensional sonography of fetal spinal cones was 97.6%. The linear regression equation between the fetal spinal cones and gestational weeks was: 1: Y-6.446X 41.547 RV 0.771. The mean time of two dimensional ultrasound group was 30 s longer than that of three dimensional ultrasound group. The 95% confidence interval (CI) 0.96 ~ 0.82% P0.001 ~ (1) ~ (4)) Two-dimensional and three-dimensional ultrasound were used to locate the position of fetal spinal cord cones and between the operators. The weighted Kappa values of Conus cones of fetal spinal cord were 0.96n0.92, respectively. Conclusion Three-dimensional horizontal central line imaging combined with skeletal mode imaging can accurately locate the position of fetal spinal cord cones.
