IADPSG诊断标准用于妊娠期糖尿病诊断的探讨

open access: yesZhongguo shiyan zhenduanxue, 2012
目的探讨妊娠期糖尿病应用国际糖尿病与妊娠研究组(IADPSG)诊断标准的合理性。方法对50g糖筛查阳性孕妇进行葡萄糖耐量实验,分别根据第7版妇产科教科书及IADPSG诊断标准诊断妊娠期糖尿病并分组,取同期非妊娠期糖尿病孕妇作为对照组,比较各组间妊娠结局。结果教科书诊断标准诊断阳性率9.7%,IADPSG诊断标准诊断阳性率12.3%。,按IADPSG诊断标准属于漏诊组的剖宫产率、子痫前期、羊水过多发生率均高于对照组,新生儿窒息、新生儿低血糖、巨大儿、大于胎龄儿发生率均高于对照组 ...

全数字化乳腺摄影、数字乳腺断层摄影与DCE-MRI对乳腺肿物诊断效能的比较

open access: yesZhongshan Daxue xuebao. Yixue kexue ban, 2020
目的本文旨在对比全数字化乳腺摄影(FFDM),数字乳腺断层摄影(DBT)及动态增强磁共振成像(DCE-MRI)对不同腺体中乳腺肿物的诊断效能。方法回顾性分析49例同时行FFDM、DBT及MRI检查的乳腺病变患者的56个病灶,依据FFDM将乳腺分为非致密型与致密型,分别依据FFDM、DBT及MRI对乳腺病变进行BI-RADS分级,4a级及以下定义为良性,4b级及以上定义为恶性。所有病人均行手术或活检获取病理诊断作为金标准。采用kappa一致性检验与受试者工作特征(ROC)曲线对比FFDM ...

多神经网络方法在变压器油色谱故障诊断中的应用

open access: yesGaoya dianqi, 2005
电力变压器的故障诊断对于变压器的维护起着至关重要的作用,诊断的可信度能给变压器维护提供更好的依据。为了克服单个神经网络不能给出诊断结果可信度的缺点,将多神经网络方法引入到变压器油色谱故障诊断中,利用多个神经网络对变压器诊断结果的方差给出了诊断结果的可信度;同时将多个网络输出的平均作为网络的诊断结果,减少了网络诊断的误差,提高了诊断的准确率。故障变压器实例验证了多神经网络方法的有效性。
