锥形束CT腮腺造影技术对腮腺非肿瘤性疾病的诊断价值

The diagnostic value of cone-beam CT sialography for non-neoplastic diseases of the parotid gland

目的 :评价锥形束CT(CBCT)腮腺造影技术在腮腺非肿瘤性疾病中的影像学诊断价值。方法 :对50例腮腺区反复肿胀的患者行常规检查后,再行CBCT腮腺造影检查并进行腮腺导管三维重建。结果:50例患者中,30例诊断为慢性阻塞性腮腺炎,12例诊断为慢性复发性腮腺炎,8例诊断为舍格伦综合征。所有患者的CBCT腮腺造影均清楚显示腺体主导管的长短、粗细以及有无充盈缺损。对于慢性复发性腮腺炎以及舍格伦综合征患者,可以很清楚地显示3~4级分支导管的形态。结论 :CBCT腮腺造影可用于诊断腮腺非肿瘤性疾病,多角度了解腺体和导管的病变。

PURPOSE： The aim of this study was to assess cone-beam CT （CBCT） sialography in the radiodiagnosis of non-neoplastic diseases of the parotid gland. METHODS： For patients with recurrent swelling of the parotid gland, CBCT and three-dimensional reconstruction of the parotid duct were performed after routine examination. RESULTS： Of 50 patients, 30 were diagnosed as chronic obstructive parotitis, 12 were diagnosed as chronic recurrent parotitis and 8 were diagnosed as Sjogren＇s syndrome. In these patients, CBCT sialography could clearly show the length, width, and filling defect of the parotid gland. For patients with chronic recurrent parotitis and Sjogren＇s syndrome, CBCT sialography can display the tertiary to quaternary branches of the parotid gland clearly. CONCLUSIONS： CBCT sialography can he used in the diagnosis of non-neoplastic diseases of the parotid gland, and CBCT sialography can provide multidimensional images of the lesion of the gland and duct.
