实时超声弹性成像评分诊断子宫肌瘤变性的ROC分析

目的 采用实时超声弹性成像技术对子宫肌瘤患者进行评分，并对诊断出的子宫肌瘤变性ROC分析进行研究与分析，从而探讨出实时超声弹性成像技术对于变性子宫肌瘤的诊断价值。方法 选取笔者医院于2014年4月~2016年6月期间收治的子宫肌瘤住院患者85例（118个病灶），采用实时超声弹性成像技术进行评分，术后进行病理检查，确认子宫肌瘤是否发生变性，将病理结果与弹性成像评分进行统计与比较，最后绘制ROC曲线进行分析其诊断价值。结果 确诊为变性子宫肌瘤的有20个，占16.95%，其中超声弹性图像评分为2~3分的有14个，占其中的70.0%；未变性子宫肌瘤的有98个，占83.05%，其中超声弹性图像评分为4分的有92个，占其中的93.9%。子宫肌瘤未变性的判断以弹性图像评分4分作为标准进行，其准确性为92.2%，特异性为68.7%，敏感度为96.2%，阳性以及阴性预测价值分别为94.1%和76.3%。子宫肌瘤变性的判断以弹性图像评分≤ 3分作为标准进行，其准确性为92.2%，特异性为96.2%，敏感度为68.7%，阳性以及阴性预测价值分别为76.3%和94.1%。结论 实时超声弹性成像技术为临床上诊断子宫肌瘤变性与否的一种有效可行的新型超声诊断技术，并通过ROC曲线分析提示弹性成像技术对于鉴别变性子宫肌瘤与未变性子宫肌瘤具有积极的价值。

ROC Analysis of the Diagnosis of Uterine Myoma Degeneration was Diagnosed by the Real-time Ultrasound Elastic Imaging Score

Objective Using real-time ultrasound elastic imaging technique to score patients with uterine fibroids, and The ROC analysis of the diagnosis of uterine myoma degeneration was studied and analyzed, so as to explore a technique of real-time ultrasound elasticity imaging diagnostic value for denatured uterine fibroids. Methods Selected from April 2014 to June 2016 hospitalized patients with uterine fibroids treated during the period of 85 cases (118 lesions), Using real-time ultrasonic elastic imaging technique to score, postoperative pathological examination was performed to confirm whether the uterine myoma degeneration occurs, the pathological results were compared with Elastic imaging score. Finally, the ROC curve was drawn to analyze its diagnostic value. Results There were 20 patients diagnosed with transsexual uterine fibroids, accounting for 16.95%, with 14 of the ultrasonic elastic images scored from 2 to 3 points, and 70.0% of them. There were 98 non-transgendered uterine fibroids, accounting for 83.05% of the total. Among them, the ultrasonically elastic images were scored in 92, accounting for 93.9% of the total. The determination of the undenatured of uterine fibroids was performed on the basis of the elastic image score=4, its accuracy is 92.2%, specificity of 68.7%, the sensitivity was 96.2%, the positive and negative predictive value of 94.1% and 76.3% respectively. The judgment of uterine fibroid degeneration was carried out as standard by the elastic image score of less than 3, its accuracy is 92.2%, specificity of 96.2%, the sensitivity was 68.7%, the positive and negative predictive value of 76.3% and 94.1% respectively. Conclusion Real-time ultrasonic elastography is an effective and feasible new ultrasonic diagnostic technique for diagnosing uterine fibroid degeneration in clinic, and through the ROC curve analysis, it is suggested that the elastic imaging technique has positive value for the identification of transsexual uterine fibroids and non-transgendered uterine fibroids.
