High-resolution ultrasound is the first line examination for parotid gland diffuse disease and focal lesions, normally using grey-scale and colour-Doppler ultrasound. Unfortunately, grey-scale and colour-Doppler ultrasound features of benign and malignant salivary gland lesions may overlap, particularly with benign tumors, where pleomorphic adenomas are often indistinguishable from malignant lesions. With atypical lesions, contrast-enhanced magnetic resonance imaging is usually the second level imaging modality requested. The introduction of ultrasound contrast agents has opened further possible perspectives to improve the interpretation of parotid diseases, particularly the differentiation between benign and malignant lesions. We present a review of the current literature on contrast-enhanced ultrasound for the assessment of parotid gland lesions, considering all characteristics of the technique, evidence of usefulness, future perspectives and limitations.
高分辨率超声是腮腺弥漫性疾病和局灶性病变的一线检查方法，通常采用灰阶超声和彩色多普勒超声。不幸的是，涎腺良性和恶性病变的灰阶超声及彩色多普勒超声特征可能会重叠，尤其是良性肿瘤，多形性腺瘤常与恶性病变难以区分。对于不典型病变，通常会要求进行对比增强磁共振成像作为二级成像方式。超声造影剂的引入为改善腮腺疾病的诊断，尤其是鉴别良性和恶性病变，开辟了更多可能的途径。我们对目前关于超声造影评估腮腺病变的文献进行综述，考虑该技术的所有特点、有效性证据、未来前景及局限性。
