【摘要】：目的探討剪切波彈性成像在不同大小頸部淋巴結(jié)良惡性鑒別中的診斷價值。方法對80例患者共125個頸部淋巴結(jié)進行常規(guī)超聲及剪切波彈性成像檢查,根據(jù)淋巴結(jié)長徑分為3組(組I:≤1cm,組Ⅱ:1~2cm,組Ⅲ:2cm),以手術(shù)切除后獲得的病理結(jié)果為診斷金標準。結(jié)果 3組中良惡性淋巴結(jié)最大彈性模量值之間的差異具有統(tǒng)計學意義,組I和組Ⅲ的約登指數(shù)和陽性似然比大于組Ⅱ,組I和組Ⅲ的陰性似然比小于組Ⅱ,組I的特異度最高。結(jié)論最大彈性模量值對長徑≤1cm和長徑2cm淋巴結(jié)的診斷價值1~2cm的淋巴結(jié),對于長徑≤1cm的淋巴結(jié)的特異度更高。有望對轉(zhuǎn)移性淋巴結(jié)的早期篩查提供幫助。
[Abstract]:Objective to evaluate the diagnostic value of shear wave elastography in differential diagnosis of benign and malignant cervical lymph nodes. Methods A total of 125 cervical lymph nodes of 80 patients were examined by conventional ultrasound and shear wave elastography. According to the length of lymph nodes, they were divided into 3 groups (group I: 鈮，
