摘要 目的探讨腮腺放射性核素检查在干燥综合征(ss)诊断中的意义。方法采用单光子发射计算机扫描仪.对39例原发性ss患者、28例类风湿关节炎(RA)患者和21例正常人进行了唾液腺核素检查,计算腮腺时间-放射性曲线的有关功能参数。结果3组间时间-放射性曲线形态异常发生率差异有统计学意义(X^2=36.06,P〈0.01),原发性ss组发生率最高,为92、31(36/39)。原发性ss组和RA继发ss组的部分曲线参数:摄取比UR1-3、最大摄取量Umax、达峰时间Wpeak及半排时间T1/2和正常组间的差异有统计学意义(P〈0.05)。所有发生龋齿的患者中,时间-放射性曲线形态异常发生率、T1/2异常发生率明显高于无龋齿组(P〈0.05),Umax明显低于无龋齿组间(P〈0.05)。类风湿因子(RF)与UR1-3,间呈负相关(r=-0.47,P=〈0.05)。结论唾液腺核素检查在原发性SS、RA继发ss的诊断中具有重要的意义,尤其注意曲线形态、Tpeak和T1/2的异常。
