目的 :探讨腮腺占位性病变的超声弹性成像表现。方法 :分析43例(48个病灶)腮腺占位性病变的超声弹性成像表现,将图像分为0~Ⅳ级,并与病理结果作对比。采用SPSS 13.0软件包对数据进行统计学分析。结果:良性病灶组弹性分级81.1%(30/37)为Ⅰ~Ⅱ级,而恶性病灶组弹性分级72.7%(8/11)为Ⅲ~Ⅳ级。2组病灶的弹性分级情况差异具有统计学意义(P﹤O.05)。结论:不同腮腺占位性病变的超声弹性图具有特征性表现,有助于腮腺良、恶性占位性病变的鉴别诊断。
Objective: To investigate the elastography of parotid space-occupying lesions. Methods: The elastography features of parotid gland lesions in 43 cases (48 lesions) were analyzed. The images were divided into 0 ~ Ⅳ grade and compared with the pathological results. Data were statistically analyzed using SPSS 13.0 software package. Results: In the benign lesion group, 81.1% (30/37) were grade Ⅰ ~ Ⅱ, while those in malignant group were grade Ⅲ ~ Ⅳ (72.7%, 8/11). The differences of elastic grading between the two groups were statistically significant (P <0.05). CONCLUSIONS: The sonographic elastography of different parotid space-occupying lesions has characteristic features that contribute to the differential diagnosis of benign and malignant parotid lesions.
