摘　　要：Objective To observe the cervical elasticity of healthy adult nulliparous women at different age groups and different stages of menstrual cycle with E-Cervix imaging technology.Methods A total of 218 healthy adult nulliparous women who underwent transvaginal ultrasound examination for routine physical examination were retrospectively enrolled,including 103 in follicular phase,78 in ovulation phase and 37 in luteal phase.Cervical canal length(CL)and E-Cervix elasticity parameters were compared among different age groups and different stages of menstrual cycle,including elasticity contrast index(ECI),hardness ratio(HR),cervical internal and external orifice strain values(IOS and EOS)and IOS/EOS ratio.Results No significant difference of CL nor cervical elasticity parameters was detected among healthy adult nulliparous women at different age groups(all P>0.05).There were significant differences of ECI,HR and IOS among different menstrual cycle stages(all P<0.05),among which women in follicular phase had higher ECI and IOS but lower HR than those in luteal phase(all P<0.05).Conclusion No significant difference of cervical elasticity existed among healthy adult nulliparous women at different age groups.Meanwhile,cervical elasticity of healthy adult nulliparous women changed during menstrual cycle,in follicular phase had higher ECI and IOS but lower HR than in luteal phase.目的基于E-Cervix成像技术观察不同年龄段及月经周期阶段健康成年未育女性宫颈弹性。方法回顾性分析因常规体检而接受经阴道超声检查的218名健康成年未育女性,其中103名处于卵泡期、78名处于排卵期、37名处于黄体期;比较不同年龄段及月经周期阶段宫颈管长度(CL)及宫颈E-Cervix弹性参数,包括弹性对比指数(ECI)、硬度比值(HR),宫颈内、外口应变值(IOS、EOS)及IOS/EOS比值。结果各年龄段健康成年未育女性CL及宫颈弹性参数差异均无统计学意义(P均>0.05);处于月经周期不同阶段女性ECI、HR及IOS差异均有统计学意义(P均<0.05),其中,卵泡期女性ECI及IOS大于、而HR小于黄体期(P均<0.05)。结论不同年龄段健康成年未育女性宫颈弹性无明显差异;健康成年未育女性宫颈弹性随月经周期而变化,卵泡期ECI及IOS大于、而HR小于黄体期。
