【摘要】：目的初步探討超聲內(nèi)鏡實(shí)時(shí)組織彈性成像及彈性應(yīng)變率比值(SR)對(duì)消化系腫瘤病灶良惡性的鑒別診斷價(jià)值。方法對(duì)26例患者32個(gè)消化系統(tǒng)實(shí)質(zhì)性腫瘤病灶進(jìn)行超聲內(nèi)鏡實(shí)時(shí)彈性成像,采用5分法進(jìn)行彈性成像評(píng)分;測(cè)量病灶與周圍對(duì)照組織的SR,并進(jìn)行組間比較。結(jié)果以評(píng)分≤2分的病灶為良性病灶,評(píng)分≥3分的病灶為惡性病灶,良惡性病灶組的超聲彈性評(píng)分對(duì)比差異有顯著性(P0.05),超聲內(nèi)鏡彈性成像診斷消化系惡性腫瘤的敏感性87.0%,特異性88.9%,準(zhǔn)確性87.5%。良性病灶組SR范圍為0.01~7.33,中位SR為7.39;惡性病灶組SR范圍為1.00~47.66,中位SR為20.07,良性病灶組的SR顯著低于惡性病灶組的SR,兩者的差異有顯著性(P0.05)。結(jié)論消化系腫瘤良惡性組織彈性成像呈不同的圖像特征,超聲內(nèi)鏡實(shí)時(shí)組織彈性成像評(píng)分及SR有助于消化系腫瘤良惡性的鑒別診斷。EUS彈性成像不能代替FNA,但是可以協(xié)助FNA靶向活檢,提高活檢的陽性率。
[Abstract]:Objective to evaluate the value of EUS real time tissue elastography and elastic strain rate ratio (SR) in the differential diagnosis of benign and malignant lesions in digestive system tumors. Methods EUS real-time elastography was performed on 32 digestive system solid tumor lesions in 26 patients. The SR, of the lesions and the surrounding control tissues were measured and compared with each other. Results the benign lesions with a score of 鈮，
