有多种放射性核素成象方法对处理胃肠疾病有用。本文评论四种临床应用的放射性核素检验方法,即放射性核素食管输送试验、胃排空试验、胃食管返流试验及胃肠道出血试验。放射性示踪物为胃肠道病理生理的检验,特别是食管、胃运动功能定量测定,提供了极好的条件。闪烁扫描术是非侵入性的,合乎生理,简单易行,可以重复,并可提供在处理病人时所需的功能方面的定量的测验结果。新的放射性药物改进了成象的质量,提高了诊断的正确度。
A variety of radionuclide imaging methods are useful for treating gastrointestinal disorders. This article reviews four clinical radionuclide test methods, namely radionuclide esophageal delivery test, gastric emptying test, gastroesophageal reflux test and gastrointestinal bleeding test. Radiological tracer for the gastrointestinal pathophysiology test, especially esophageal and gastric motor function quantitative determination, provided an excellent condition. Scintigraphy is non-invasive, physiologically simple, reproducible, and provides quantitative test results in the functional aspects required to treat patients. New radiopharmaceuticals improve imaging quality and improve diagnostic accuracy.
