【摘要】：目的:探讨ESWAN幅值图在卵巢子宫内膜异位囊肿诊断中的价值。方法:由两位影像诊断医师对36例经手术病理证实的卵巢囊性病变(子宫内膜异位囊肿18例30个病灶、其他囊性病变18例24个病灶)患者的常规MRI及ESWAN图像进行独立评估,重点观察ESWAN序列mIP幅值图上囊性病变囊壁内是否有信号缺失。计算ESWAN序列mIP幅值图上囊壁内信号缺失鉴别卵巢子宫内膜异位囊肿和其他囊性病变的敏感度、特异度、阳性和阴性预测值,对两位医师的评估结果进行一致性检验。结果:两位医师在评估ESWAN序列mIP幅值图囊性病变囊壁内是否有信号缺失中,52个(96.3%,52/54)病灶的评估结果是一致的,Kappa系数为0.925,一致性较好。ESWAN序列mIP幅值图上囊壁内信号缺失鉴别卵巢子宫内膜异位囊肿和其他囊性病变的敏感度、特异度、阳性预测值和阴性预测值分别为90.0%、91.7%、93.1%、88.0%。结论:ESWAN幅值图能为卵巢子宫内膜异位囊肿的诊断及鉴别诊断提供重要信息,有助于提高卵巢子宫内膜异位囊肿的诊断符合率。
[Abstract]:Objective: To investigate the value of ESWAN amplitude in ovarian endometriosis diagnosis. Methods: by two diagnostic imaging physician of 36 patients with pathologically proved ovarian cystic lesions (18 cases with endometrial cysts of 30 lesions and other cystic lesions in 18 cases with 24 lesions) independent evaluation of conventional MRI and ESWAN the image of patients, focusing on ESWAN sequence mIP amplitude on cystic lesions are cystic wall. Signal loss calculation of ESWAN sequence of mIP amplitude signal voids within the cystic wall to differentiate ovarian endometriomas and other cystic lesions, the sensitivity, specificity, positive and negative predictive value, assessment of two the doctors of the consistency test results. Results: two physicians in the assessment of ESWAN sequence of mIP amplitude sabretache diseases have signal loss in the cyst wall, 52 (96.3%, 52/54) lesions of the evaluation results is consistent with the Kappa coefficient was 0.92 5, consistent with.ESWAN sequence of mIP amplitude signal voids within the cystic wall to differentiate ovarian endometriomas and other cystic lesions of the sensitivity, specificity, positive predictive value and negative predictive value were 90%, 91.7%, 93.1%, 88.0%.. Conclusion: the amplitude of ESWAN map can provide important information for the diagnosis and differential diagnosis ovarian endometriosis cyst, is helpful to improve the diagnosis of ovarian endometriosis with rate.

【正文快照】： 卵巢子宫内膜异位囊肿(endometrioma,EMO)是妇科常见疾病,卵巢EMO(以下简称EMO)内反复出血及破裂可以导致严重的盆腔粘连和不孕,严重影响育龄妇女的健康和生活质量,因此对其早期诊断有着重要的临床意义。尽管超声是妇科疾病的首选影像学检查方法,但是MRI在诊断EMO上较超声特异
