【摘要】:目的: 建立以甲狀腺微小結節(jié)超聲診斷特征為變量的Logistic回歸模型,評價二維灰階超聲、彩色多普勒超聲、超聲彈性成像及超聲造影成像模式在甲狀腺微小實性結節(jié)中的診斷價值。 方法: 回顧性分析經(jīng)手術病理證實的130例共142個最大直徑≤1.0cm的病灶且無甲狀腺彌漫性病變患者的臨床資料,142個病灶中,其中良性68個,惡性74個,對結節(jié)各項超聲診斷指標采用多因素回歸分析方法,建立Logistic回歸模型,繪制ROC曲線并計算曲線下面積。 結果: Logistic逐步回歸分析顯示結節(jié)內(nèi)部微鈣化,縱橫比,造影晚期回聲及彈性評分4個變量進入回歸模型,該Logistic回歸模型對最大直徑≤1.0cm的甲狀腺結節(jié)良惡性預報的正確率為92.1%(129/142),ROC曲線下面積為0.944。 結論: 二維和彩色多普勒超聲結合組織彈性成像技術及實時超聲造影技術在最大直徑≤1.0cm的甲狀腺良惡性結節(jié)的鑒別診斷中具有較高的臨床應用價值。
