The Value of High Frequency Ultrasound in the Diagnosis of Parotid Tumor

目的 :探讨高频超声诊断腮腺区肿块性病变的价值。材料与方法 :回顾性分析 37例经病理 /手术证实的腮腺区肿块。结果 :术前B超诊断正确 32例 ,其准确率为 86 5 % ,误诊 5例 ,误诊率为 13 5 %。结论 :高频超声诊断腺腺区肿块 ,准确率高 ,操作简便且能显示肿瘤良、恶性 ,并可进行腮腺内。

Purpose: The diagnostic value of high frequency ultrasound was studied in evaluating parotid lesion. Materials and Method: 37 cases of parotid tumors proved by pathology were retrospectively studied. Results: before operation 32 cases were correctly diagnosed by B mode sonography, the diagnostic accuracy was 86.4%, 2 cases wree misdiagnosed. Conceusion: High frquency ultrasound in the diagnosis of parotid gland tumor was economically and practically useful, the diagnostic accuracy was high. and simple study could identity malignant and benigh tumors and be used to localize Parotid gland tumors.
