The important points in the imaging examination of disorders in the salivary gland and the surrounding area vary based on the types of lesions. In cases of tumorous lesions, malignancy and localization of lesions and positional relationship with the blood vessels and nerves are important. In cases of inflammation and autoimmune diseases, morphological changes in the salivary gland and the function are important. The purpose of this study was to define the purpose and selection procedures of MRI and other imaging examinations of each disease in the salivary gland and the surrounding area, and to support diagnostic imaging, by collecting image information of each disease.Seventy-two cases, in which histopathological or clinical diagnoses were established, were evaluated. The breakdown was benign salivary gland tumors (38), malignant salivary gland tumors (8), malignant lymphomas (7), malignant tumors (6), benign tumors (5), cysts (4), and inflammatory lesions (4).Echography is useful for differentiating tumorous lesions from inflammatory diseases, and is essential for screening disorders in the salivary gland and the surrounding area at the first examination. Plain X-CT was not useful due to decreased contrast between the salivary gland and the surrounding tissue. Sialography was useful for investigating the relationship between the localization of lesions and the glands ; however, it was not useful for qualitative diagnosis. RI scintigraphy was useful for the specific diagnosis of adenolymphoma. MRI was the most useful examination, because much information regarding the localization of lesions and qualitative diagnosis was obtained.Although improvement is required in the images of MR-sialography, this method may be an alternative examination for sialography. Statistical calculation of the frequency and the rate of fitness of diseases was not possible due to the imbalance of the case number of each disease and the number of examined cases.

唾液腺及周围病变的影像学检查要点因病变类型而异。在肿瘤病变的情况下，肿瘤的恶性程度和病变的定位以及与血管和神经的位置关系是重要的。在炎症和自身免疫性疾病的情况下，唾液腺的形态变化和功能是重要的。本研究的目的是通过收集各种疾病的图像信息，明确唾液腺及周围各疾病的MRI及其他影像学检查的目的和选择程序，支持诊断成像。对72例经组织病理学或临床诊断的病例进行评估。分类为良性唾液腺肿瘤38例，恶性唾液腺肿瘤8例，恶性淋巴瘤7例，恶性肿瘤6例，良性肿瘤5例，囊肿4例，炎性病变4例。超声检查有助于区分肿瘤病变和炎症性疾病，在第一次检查时筛查唾液腺和周围区域的疾病是必不可少的。由于唾液腺和周围组织的对比减弱，X-CT平片没有用处。唾液造影有助于研究病变的定位与腺体之间的关系；但对定性诊断没有帮助。磁共振显像对腺淋巴瘤的特异性诊断是有用的。MRI是最有用的检查，因为它获得了很多关于病变定位和定性诊断的信息。虽然磁共振唾液造影的图像需要改进，但这种方法可能是唾液造影的另一种检查方法。由于每种疾病的病例数与检查病例数不平衡，无法对疾病的频率和适合率进行统计计算。
