放射性核素唾液显像的临床应用进展

The progress of radionuclide salivagram for clinical application

摘要: 放射性核素唾液显像是将⁹⁹Tc^m-硫胶体滴入口腔内，形成⁹⁹Tc^m-硫胶体唾液混合物，利用放射性核素显影仪获得唾液流经途径影像，能够无创性探测吞咽引起的肺吸入。临床怀疑吸入性肺炎时，应首选放射性核素唾液显像进行诊断。

Abstract: The radionuclide salivagram can be used to detect the pulmonary aspiration occurred during ⁹⁹Tc^m-sulfur colloid swallowing noninvasively. In patients in whom the main clinical concern is pul-monary aspiration, the radionuclide salivagram should first be taken into consideration for diagnosis of pul-monary aspiration.
