| 摘 要： | 目的研究放射性药物唾液腺显像定量分析对干燥综合征的诊断价值.方法静脉注射99TcmO4-370 MBq,前位采集唾液腺动态图像,连续50 min.在40 min时,给受检者口含Vit C 0.5g刺激唾液腺的分泌.根据唾液腺动态图像,建立腮腺和颌下腺的时间-放射性曲线,并计算有关功能参数.结果干燥综合征患者腮腺和颌下腺的摄取比值(UR)分别为2.8±1.2和1.6±0.7,正常对照组分别为5.1±1.4和3.4士0.6,两组比较有显著性差异(P＜0.01);干燥综合征患者腮腺和颌下腺的Tmin分别为3.9±2.5和5.1±2.3明显高于正常对照组的1.8±1.1和2.4±1.4(P＜0.01);干燥综合征患者腮腺和颌下腺的Tmax与正常对照组无显著性差异(P＞0.05).结论测定UR和Tmin是判断干燥综合征患者腮腺及颌下腺功能十分灵敏的指标;而测定干燥综合征患者腮腺及颌下腺的Tmax临床价值不大.
