| 目的 评价超声弹性成像组织弥散定量分析技术预测宫颈功能不全（CIC）的价值。方法 收集临床诊断为CIC的18例患者（CIC组）和正常女性20名（对照组），于非孕期行经阴道超声检查，测量宫颈长度和厚度，采用超声弹性成像组织弥散定量分析技术获得11个宫颈弹性特征量值，包括应变均值、标准偏差、蓝色区域所占百分比（% AREA）、复杂度、偏度、峰度、对比度、均等性、杂乱度、一致性及相关性，比较2组间的差异，绘制ROC曲线获得对CIC有诊断价值的指标。结果 2组间弹性特征量应变均值、标准偏差、% AREA、复杂度、偏度、对比度、均等性、一致性差异均有统计学意义（P均<0.05），而宫颈长度、厚度和峰度、杂乱度、相关性差异均无统计学意义（P均>0.05）。ROC曲线分析结果显示，% AERA、复杂度和均等性对CIC具有诊断价值（AUC=0.83、0.82、0.71），其临界值分别为% AERA=34.85、复杂度=20.84、均等性=3.20，其中% AREA敏感度最高（94.74%），复杂度特异度最高（73.08%）。结论 超声弹性成像组织弥散定量分析技术预测CIC具有一定价值。 |

| Objective To explore the value of ultrasonic elastic quantitative analysis technique of organization diffusion in the prediction of cervical incompetence (CIC). Methods Totally 18 patients with clinical diagnosed CIC (CIC group) and 20 normal women (control group) were collected. The length and thickness of the cervix were measured with transvaginal ultrasonography during non-pregnancy, and 11 elastic characteristics of the cervix were obtained using ultrasonic elastic quantitative analysis of organization diffusion technique, including mean relative strain value (MEAN), standard deviation of relative strain value (SD), ration of pixel area under (%AREA), complexity (COMP), skewness (SKEW), kurtosis (KURT), contrast (CONT), entropy (ENT), inverse difference moment (IDM), angular second moment (ASM) and correlation (CORR). The differences between the two groups were compared, and the ROC curve was used to obtain indicators that had diagnostic value for CIC. Results The differences of MEAN, SD,%AREA, COMP, SKEW, CONT, ENT and ASM were statistically significant between the 2 groups (all P<0.05). There was no significant difference in the length or thickness of cervix, nor of KURT, IDM, CORR (all P>0.05). ROC curve analysis showed that%AERA, COMP and ENT had diagnostic value for CIC (AUC=0.83, 0.82, 0.71). The thresholds of%AERA, COMP, ENT was 34.85, 20.84 and 3.20, respectively. Among them, the sensitivity of%AREA was the highest (94.74%), and the specificity of COMP was the highest (73.08%). Conclusion Ultrasonic elastic quantitative analysis of organization diffusion technique has certain value in prediction of CIC. |
