摘要目的评价切变波弹性影像(SWE)诊断大唾液腺局灶性病变的作用。方法60个病变(腮腺49个,颌下腺11个)在超声引导下针吸细胞学活检前接受了常规超声(灰阶与多普勒超声)和SWE检查。切变弹性系数(僵硬度)定量指数与细胞学结果对照。结果55个病变为良性(21个多形性腺瘤,18个Warthin瘤
Abstract Objective To evaluate the role of shear wave elastography (SWE) in the diagnosis of focal large salivary glands. Methods Sixty-six lesions (49 parotids and 11 submandibular glands) underwent conventional ultrasound (grayscale and Doppler ultrasound) and SWE before needle aspiration biopsy under ultrasound guidance. Shear elastic modulus (stiffness) quantitative index and cytological results of the control. Results 55 lesions were benign (21 pleomorphic adenomas, 18 Warthin tumors
