三维ＣＴ成像技术在涎腺造影术中的应用尚未见国内外有关文献报道。作者从９４年始，对５例涎腺疾病患者进行了涎腺造影，并进行三维ＣＴ重建成像，三维ＣＴ成像在涎腺疾病诊断中，通过腺体导管注入造影剂，表面显示法就可直接提取腺体组织，立体地显示了腺体组织的外形、大小及其与周围组织的关系，多形性腺瘤对腺体组织的直接压迫引起腺体组织的缺损，但其边缘光整。腮腺结核对腺体组织的影响似呈珊瑚状。此外，通过切割方法还可以清楚显示腺体导管的长短，粗细以及有无充盈缺损等。
The application of three-dimensional CT imaging in salivary gland angiography has not been reported in the literature at home and abroad. From the beginning of 1994, salivary gland angiography was performed in 5 patients with salivary gland disease and three-dimensional CT reconstruction imaging was performed. In the diagnosis of salivary gland disease, by injecting contrast agent through the gland duct, three-dimensional CT imaging can be directly extracted by surface display method Glandular tissue, three-dimensional display of the glandular tissue shape, size and its relationship with the surrounding tissue, pleomorphic adenoma direct compression of the glandular tissue caused by the loss of glandular tissue, but its edge finishing. Parotid gland tuberculosis on the impact of glandular tissue was coral-like. In addition, the cutting method can also clearly show the length of the gland duct, thickness, and whether the filling defect and so on.
