摘要超声为腮腺病变诊断的一线影像检查方法,然而,单凭超声检查不能鉴别良性与恶性病变。由于细针针吸细胞学活检(FNAC)结果正确率并非100%,而腮腺部分/全部切除又有面神经麻痹与Frey综合征的危险,能鉴别肿瘤良恶性的影像技术具有重大价值。超声弹性图为一新的影像技术,已用于 Abstract Ultrasound is a first-line imaging method for the diagnosis of parotid lesions. However, ultrasonography alone can not distinguish between benign and malignant lesions. Because fine needle aspiration biopsy (FNAC) results are not 100% correct, and parotid partial / total resection and facial nerve paralysis and Frey syndrome risk, to identify benign and malignant imaging techniques of great value. Elastogram is a new imaging technique that has been used
