Photographic subtraction used in the examination of salivary glands was compared with conventional sialography. Subtraction images obtained from the duct system of parotid glands demonstrated the same images as were obtained by conventional sialography. In duct system of the submaxillary glands, however, the conventional sialograms were clearer than those images obtained by subtraction procedures. Subtraction images could provide the outward form of salivary glands, especially in the parotid glands. In most cases, sialography with subtraction provides valuable informations in diagnosing salivary gland diseases. But, the results showed that the necessity of applying this modality must be examined carefully.
将用于唾液腺检查的摄影减影法与传统唾液腺造影术进行了比较。从腮腺导管系统获得的减影图像显示出与传统唾液腺造影术相同的图像。然而，在下颌下腺导管系统中，传统唾液腺造影片比通过减影程序获得的图像更清晰。减影图像可以提供唾液腺的外形，尤其是在腮腺中。在大多数情况下，减影唾液腺造影术在诊断唾液腺疾病方面提供了有价值的信息。但是，结果表明，必须仔细检查应用这种方法的必要性。
