| 目的 探讨常规超声（US）联合剪切波弹性成像（SWE）在腮腺多形性腺瘤与Warthin瘤鉴别诊断中的价值，并与MRI对比分析诊断效能。方法 选取我院经手术病理证实的81例腮腺肿瘤，其中58例多形性腺瘤和23例Warthin瘤，比较两种病变的US特征：形态、边界、强回声、无回声、血流分布、血流分级以及SWE定量参数：最大值（Emax）、平均值(Emean)、最小值(Emin)、标准差(SD)。分别建立US、SWE和US+SWE的Logistic回归模型，绘制受试者工作特征（ROC）曲线分析其鉴别多形性腺瘤和Warthin瘤诊断效能，并与MRI对比分析。结果 多形性腺瘤和Warthin瘤的声像图特征中形态、强回声、无回声、血流分布、血流分级、Emax、Emean、SD差异有统计学意义（P＜0.05）。肿块的形态、血流分级、Emax、Emean、SD是鉴别的有效参数，US、SWE和US+SWE的Logistic回归模型的ROC曲线下面积（AUC）分别为0.881、0.837、0.962。US+SWE的敏感度为85%，特异度为88%，准确度为86.2%；MRI检查的敏感度为87.27%，特异度为84%，准确度为86.2%，差异无统计学意义(P＞0.05)，两者的诊断价值较一致。结论 常规超声联合剪切波弹性成像可以提高超声鉴别诊断腮腺多形性腺瘤和Warthin瘤的能力，并且诊断效能可媲美MRI检查。 |

| Abstract: |
| Objective To explore the value of conventional ultrasound (US) combined with shear wave elastography (SWE) in the differential diagnosis of parotid pleomorphic adenoma and Warthin''s tumor, and compare the diagnostic efficiency with MRI. Methods Select 81 cases of parotid gland tumors confirmed by pathology, 58 cases of pleomorphic adenoma and 23 cases of Warthin''s tumor, Compare the US characteristics of two lesions: Shape, boundary, hyper echo, anechoic, blood flow distribution, blood flow grade and SWE quantitative parameters: Emax, Emean, Emin, SD. Results There were statistical significance in the tumor Shape, hyper echo, anechoic, blood flow distribution, blood flow grade and Emax, Emean, SD between the pleomorphic adenoma and Warthin''s tumor (P＜0.05), The area under the ROC (AUC) of the Logistic equation predicted values of US , SWE and US+SWE are 0.881, 0.837, 0.962. The diagnostic sensitivity, specificity, accuracy of US+SWE and MRI were (85%, 87.27%), (88%, 84%), (86.2%, 86.2%), The difference was not statistically significant (P＞0.05), the diagnostic value is consistent. Conclusions Conventional ultrasound combined with shear wave elastography can improve the ability of differential diagnosis pleomorphic adenoma and Warthin''s tumor of parotid, and the diagnostic efficiency is comparable to MRI. |
