摘　　要：目的分析双低CT扫描结合迭代重建技术在女性盆腔囊性病变诊断的应用价值。方法研究对象选取2018年6月至2020年6月本院收治的145例疑似盆腔囊性病变患者,分别进行常规CT扫描结合重建技术(对照组),双低CT扫描结合迭代重建技术(观察组),对比两组检查方式图像质量、符合率、AUC值,分析盆腔囊性病变的CT影像表现。结果观察组CT值(28.2±2.15)HU、图像主观评分(3.75±0.41)分高于对照组CT值(27.5±1.68)HU、图像主观评分(3.12±0.11)分,DLP(182.49±15.65)mGy·cm、CTDIvol(6.21±0.24)mGy低于对照组DLP(286.96±27.78)mGy·cm、CTDIvol(10.15±0.63)mGy(P<0.05);145例疑似者,经确诊131例,其中子宫平滑肌瘤31例,卵巢囊肿73例,卵巢囊腺瘤27例;观察组符合率97.71%高于对照组符合率80.92%(P<0.05);经ROC曲线分析,观察组、对照组预测盆腔囊性病变的AUC分别为0.952、0.814。结论采取“双低”CT扫描结合迭代重建技术,在盆腔囊性病变患者诊断过程中,取得显著的应用价值。Objective To analyze the application value of double-low CT scan combined with iterative reconstruction technology in the diagnosis of female pelvic cystic lesions.Methods 145 patients with suspected pelvic cystic lesions admitted to our hospital from June 2018 to June 2020 were selected as the research objects for routine CT scanning combined with reconstruction technology(control group)and double-low CT scanning combined with iterative reconstruction technology(Observation group),respectively.The compare the image quality,coincidence rate and AUC value of the two inspection methods were compared,and analyze the CT imaging manifestations of pelvic cystic lesions.Results The observation group's CT value(28.2±2.15)HU and image subjective score(3.75±0.41)were higher than the control group CT value(27.5±1.68)HU,image subjective score(3.12±0.11).DLP(182.49±15.65)MGy·cm and CTDIvol(6.21±0.24)mGy were lower than the control group DLP(286.96±27.78)mGy·cm,CTDIvol(10.15±0.63)mGy(P<0.05).Among 145 suspected cases,131 cases were confirmed,including 31 cases of uterine leiomyomas,73 cases of ovarian cysts,and 27 cases of ovary cystadenoma.The coincidence rate of observation group(97.71%)was higher than that of control group(80.92%)(P<0.05).ROC curve analysis should that the AUC of the observation group and the control group in predicting pelvic cystic lesions were 0.952 and 0.814,respectively.Conclusion In the diagnosis of female pelvic cystic lesions,the use of"double-low"CT scan combined with iterative reconstruction technology has achieved significant application value.
