E-cervix宫颈弹性分析技术评价非孕期正常宫颈机能的可行性

Feasibility of E-cervix cervical elasticity analysis in evaluating normal cervical function in non pregnant women

目的运用E-cervix宫颈弹性分析技术分析非孕期正常宫颈机能,探讨该技术的可行性及影响因素。方法选取2019年5月至11月于佛山市妇幼保健院超声科行阴道超声检查的213例孕前体检女性为研究对象,以宫颈正中矢状切面为初始切面,启动E-cervix技术软件包,自动获取弹性对比指数(ECI)、硬度比值(HR)、宫颈内口应变率(I0S)、宫颈外口应变率(EOS)、宫颈内外口应变比值(I0S/E0S)、宫颈长度(CL)六组参数,比较不同年龄、月经周期、BMI指数、生育史、分娩方式与各弹性参数之间的关系。结果各弹性参数与年龄无相关性(P>0.05),在不同年龄段之间各弹性参数差异无统计学意义(P>0.05);月经期、增生期、分泌期宫颈组织各弹性参数差异无统计学意义(P>0.05);体重过轻、正常、超重者各弹性参数差异无统计学意义(P>0.05);CL与BMI呈正相关(r=0.225,P<0.05),其余参数与BMI无相关性(P>0.05);无生育史者与有生育史者各弹性参数之间差异无统计学意义(P>0.05);剖宫产女性的CL[(34.22±4.96)mm]高于顺产女性[(29.03±4.14)mm],差异具有统计学意义(P<0.05),其余参数差异无统计学意义(P>0.05)。结论E-cervix技术获得宫颈弹性参数基本不受年龄、BMI指数、月经期、生育史、分娩方式的影响,可用于定量评价宫颈机能。

Objective To explore the feasibility and influencing factors of E-cervix cervical elasticity analysis technology in analyzing normal cervical function during non pregnancy.Methods 213 women who underwent vaginal ultrasound examination in the Ultrasound Department of Foshan Maternal and Child Health Hospital from May 2019 to November 2019 were selected as the research objects.Taking the median sagittal section of the cervix as the initial section,the E-cervix technology software package was started to automatically obtain the elastic contrast index(ECI),hardness ratio(HR),cervical strain rate(IOS),cervical strain rate(EOS),cervical strain ratio(IOS/EOS)and cervical length(CL).The relationship among age,menstrual cycle,BMI index,birth history,delivery mode and elastic parameters were compared.Results There was no correlation between the elastic*parameters and age,and there was no significant difference among different age groups(P>0.05);there was no significant difference in the elastic parameters of cervical tissue in menstrual period,proliferative period and secretory period(P>0.05);there was no significant difference in the elastic parameters of undenveight,normal and overweight(P>0.05);CL was positively correlated with body mass index(BMI)(r=0.225,P<0.05),there was no correlation between other parameters and BMI(P>0.05);there was no significant difference between the elastic parameters of patients with and without birth history(P>0.05);the CL of women with cesarean section[(34.22±4.96)mm]was higher than that of women with natural birth,(29.03±4.14)mm](P<0.05),and the other parameters had no statistical significance(P>0.05).Conclusions The elastic parameters of cen ix obtained by E-ccrvix technique are not affected hy cige,BMI,menstrual period,reproductive histoiT and deliveiy mode,and can be used for cjuantitative evaluation of cerviral function.
