【摘要】：目的探討Logistic回歸分析在常規(guī)超聲及CEUS診斷甲狀腺良惡性結節(jié)中的價值。方法選取經超聲引導下穿刺活檢或術后病理證實的甲狀腺結節(jié)患者218例,其中惡性結節(jié)74例,良性結節(jié)144例,觀察結節(jié)邊界、形態(tài)、縱橫比、微鈣化、回聲類型、血流分級以及CEUS增強模式等超聲特征,并對其行單因素分析,以有統(tǒng)計學意義的指標為因變量,行多因素Logistic回歸分析,建立ROC曲線。結果單因素分析顯示低回聲、形態(tài)不規(guī)則、邊界不清、縱橫比≥1、微鈣化、血流分級(Ⅰ、Ⅱ級)、不均勻增強及低增強是診斷甲狀腺惡性結節(jié)的重要指標(P均0.01)。多因素分析顯示形態(tài)不規(guī)則、微鈣化、不均勻增強及低增強是甲狀腺惡性結節(jié)的獨立預測指標(P均0.05)。以Logistic回歸模型預測甲狀腺惡性結節(jié)的準確率為82.57%,ROC曲線下面積為0.906。結論根據甲狀腺結節(jié)邊界、形態(tài)、縱橫比、微鈣化、回聲類型、血流分級以及CEUS增強特征建立的Logistic回歸模型有助于診斷甲狀腺惡性結節(jié)。
[Abstract]:Objective to evaluate the value of Logistic regression analysis in the diagnosis of benign and malignant thyroid nodules by conventional ultrasound and CEUS. Methods 218 patients with thyroid nodules confirmed by ultrasound guided biopsy or postoperative pathology were selected, including 74 malignant nodules and 144 benign nodules. The boundary, shape, aspect ratio, microcalcification and echo type of thyroid nodules were observed. Ultrasound features such as blood flow grading and CEUS enhancement mode were analyzed by univariate analysis. The multivariate Logistic regression analysis was performed to establish the ROC curve. Results univariate analysis showed that hypoechoic, irregular shape, unclear boundary, aspect ratio 鈮，
