Abstract：
Major and minor salivary gland malignancies come in various shapes and sizes. They can present as palpable masses or can be detected incidentally when imaging patients for other indications. A complete evaluation of salivary gland malignancies requires knowledge of the anatomy and various routes of spread of neoplasias. Computed tomography (CT) and MR imaging are complementary tools in this respect and offer useful information to the proceduralist. Advanced imaging (diffusion-weighted imaging and PET-CT) and other modalities (eg, ultrasound) help with characterization, although biopsy or excision is often needed for definitive tissue diagnosis.
摘要：
主要和次要唾液腺恶性肿瘤有各种形状和大小。它们可以表现为可触及的肿块，也可以在对患者进行其他适应症成像时偶然发现。全面评估唾液腺恶性肿瘤需要了解肿瘤的解剖结构和各种扩散途径。计算机断层扫描（CT）和MR成像是这方面的补充工具，可为专家提供有用的信息。高级成像（弥散加权成像和PET-CT）和其他方式（例如，超声)帮助表征，尽管明确的组织诊断通常需要活检或切除。
