目的：探讨９９ｍ锝腮腺动态显像对诊断舍格伦综合征的价值。方法：应用９９ｍ锝对临床诊断为舍格伦综合征的５２例患者进行腮腺动态显像，将所得的结果应用计算机ＲＯＩ程序进行定量分析和动态曲线分析。结果：腮腺外形较正常大者４６例（８８．４％），肿大腮腺轮廓清晰２８例（５３．８５％），轮廓模糊１８例（３４．６２％）。腮腺功能正常７例（１３．４６％），轻度受损１５例（２８．８４％），中度受损１７例（３２．６９％），重度受损１３例（２５％）。舍格伦综合征首先是腮腺分泌功能受损，并存在于多数患者４５例（８６．５３％），而摄取功能受累较晚，存在于少数较重患者５例（９．６％）。结论：９９ｍ锝动态显像是一种检查唾液腺功能很有价值的方法。
Objective: To investigate the value of 99mTcT parotid dynamic imaging in the diagnosis of Sjogren’s syndrome. Methods: Fifty-two patients with clinically diagnosed Sjogren’s syndrome were enrolled in this study. Parotid dynamic imaging was performed using 99m technetium. The results were analyzed using computerized ROI procedures for quantitative analysis and dynamic curve analysis. Results: 46 cases (88.4%) had larger parotid gland shape, 28 cases (53.85%) had clear outline of parotid gland, and 18 cases (34.62%) had blurred contour. Parotid gland function was normal in 7 cases (13.46%), mild injury in 15 cases (28.84%), moderate damage in 17 cases (32.69%) and severe damage in 13 cases (25%). Sjogren’s syndrome is the first impaired parotid secretory function, and exists in the majority of 45 patients (86.53%), while intake of late involvement, in a few severe cases in 5 patients (9.6%). Conclusion: 99m Tc dynamic imaging is a valuable method for examining salivary gland function.
