1、超聲造影在良惡性卵巢腫瘤鑒別診斷中的價(jià)值［摘要］目的觀察卵巢腫瘤在普通多普勒和超聲造影中的表現(xiàn)，分析評價(jià)超聲造影對卵巢腫瘤良惡性的診斷價(jià)值。方法選取2013年1月?2015年1月在海南省人民醫(yī)院行常規(guī)超聲檢查診斷為卵巢腫瘤患者64例為研究對象，所有患者于術(shù)前行超聲造影，結(jié)合術(shù)后病理結(jié)果，采用ROC曲線下面積比較分析兩種檢測方法的靈敏度。結(jié)果病理檢查結(jié)果顯示64例卵巢腫瘤中良性37例，惡性27例。卵巢良、惡性腫瘤的造影強(qiáng)化特點(diǎn)存在明顯差異。37例卵巢良性腫瘤中，35例造影劑緩慢強(qiáng)化，27例卵巢惡性腫瘤均表現(xiàn)為造影劑快速強(qiáng)化。與卵巢良性腫瘤相比，卵巢惡性
2、腫瘤內(nèi)造影強(qiáng)化的始增時(shí)間早，達(dá)峰時(shí)間早，灌注強(qiáng)度高，造影強(qiáng)化的時(shí)間-強(qiáng)度曲線上升支、下降支陡直。普通多普勒超聲對惡性卵巢腫瘤檢出的靈敏度為44.44%,通過超聲造影檢出惡性卵巢腫瘤的靈敏度為74.07%o普通多普勒ROC下面積為0.598,超聲造影ROC下面積為0.723o結(jié)論超聲造影有助于更準(zhǔn)確地評價(jià)腫瘤內(nèi)的血流信息，對卵巢良、惡性腫瘤的鑒別診斷及卵巢腫瘤的早期診斷有重要的參考價(jià)值。［關(guān)鍵詞］超聲造影；卵巢腫瘤；良惡性；鑒別診斷［中圖分類號］R445.1；R737.31［文獻(xiàn)標(biāo)識碼］A［文章編號]1673-7210(2016)01(a)-0117-
