Cone beam computed tomography (CBCT) is being widely used in recent years and has modernized the practice of oral and maxillofacial radiology by its inherent advantages, such as short scanning time, high resolution, and low dose of radiation to the patient. Sialography can be considered as the second step of assessment of space-occupying masses after initial diagnosis with ultrasonography. Sialography is combined with plain radiographs in routine practice. It can also be combined with advanced modalities such as computed tomography (CT), magnetic resonance imaging (MRI), and CBCT. In this report, we describe 3 cases to confirm the feasibility and superiority of sialography using CBCT and 3-dimensional (3D) images in space-occupying lesions of major salivary glands when conventional sialography is not diagnostic or MRI and CT are not easily available or affordable. CBCT sialography and its 3D images can be helpful in the diagnosis of space-occupying lesions of major salivary glands.
近年来，锥形束计算机断层扫描（CBCT）得到了广泛应用，凭借其固有的优势，如扫描时间短、分辨率高以及对患者辐射剂量低等，使口腔颌面放射学实践实现了现代化。唾液腺造影术可被视为在超声初步诊断后对占位性肿块进行评估的第二步。在常规实践中，唾液腺造影术与平片相结合。它也可与计算机断层扫描（CT）、磁共振成像（MRI）和CBCT等先进模式相结合。在本报告中，我们描述了3例病例，以证实当传统唾液腺造影术无法诊断或MRI和CT不易获得或费用过高时，使用CBCT和三维（3D）图像进行唾液腺造影术在主要唾液腺占位性病变中的可行性和优越性。CBCT唾液腺造影术及其3D图像有助于诊断主要唾液腺的占位性病变。
