Our aim was to review the clinical applications of diffusion-weighted magnetic resonance imaging in the head and neck. Diffusion-weighted magnetic resonance imaging plays a role in the differentiation of benign from malignant head and neck tumors, squamous cell carcinoma from lymphoma, and metastatic from benign lymphadenopathy as well as in the selection of the biopsy site. It can be used for the differentiation of recurrent tumors from posttreatment changes and in monitoring the patient after radiotherapy. It helps in the differentiation of necrotic tumors from abscesses. Additionally, it can be used for the diagnosis and grading of diffuse autoimmune diseases, such as Sjogren and Graves diseases.
我们的目的是回顾扩散加权磁共振成像在头颈部的临床应用。扩散加权磁共振成像在头颈部良恶性肿瘤的鉴别、鳞状细胞癌与淋巴瘤的鉴别、转移性淋巴结病与良性淋巴结病的鉴别以及活检部位的选择中发挥作用。它可用于鉴别复发性肿瘤与治疗后改变，并在放疗后监测患者。它有助于鉴别坏死性肿瘤与脓肿。此外，它还可用于弥漫性自身免疫性疾病（如干燥综合征和格雷夫斯病）的诊断和分级。
