彩色多普勒超声在浅表软组织肿块诊断中的应用分析

Application Analysis of Color Doppler Ultrasonography in the Diagnosis of Superficial Soft Tissue Masses

本研究探讨彩色多普勒超声在浅表软组织肿块诊断中的应用价值。选取浅表组织肿块患者210例,其中良性病变患者172例,恶性病变患者38例,给予彩色多普勒超声检查。结果显示,恶性病变形态不规则、内部不均匀低回声、边界模糊、内部血流丰富比例明显高于良性病变(P<0.05);恶性病变病灶收缩期峰值流速(Vmax)和阻力指数(RI)明显高于良性病变(P<0.05),病灶最大长径/最大短径(L/S)明显低于良性病变(P<0.05);年龄、形态、内部回声、边界、内部血流、Vmax和RI建立Logistic回归方程,其诊断恶性病变的ROC曲线下面积为0.910(P<0.05),灵敏性和特异性达到84.00%和96.00%。可见彩色多普勒超声在浅表软组织肿块良恶性诊断中有较好的应用价值。

The purpose of this study was to explore the application value of color Doppler ultrasound in the diagnosis of superficial soft tissue masses.210 patients with superficial tissue masses were selected,172 were benign and 38 were malignant,color Doppler ultrasonography was given.The proportion of malignant lesions with irregular shape,internal inhomogeneous hypoechoic,fuzzy boundary and rich internal blood flow was significantly higher than that of benign lesions(P<0.05).The peak systolic velocity(Vmax)and resistance index(RI)of malignant lesions were significantly higher than that of benign lesions(P<0.05),the maximum length diameter/maximum short diameter(L/S)of lesions was significantly lower than that of benign lesions(P<0.05).Logistic regression equation was established for age,shape,internal echo,boundary,internal blood flow,Vmax and RI,the area under the ROC curve of this model for the diagnosis of malignant lesionswas 0.910(P<0.05),and the sensitivity and specificity were 84.00%and 96.00%.Color Doppler ultrasound has good application value in the diagnosis of benign and malignant superficial soft tissue masses,which is worthy of clinical use.
