介绍锝气体制备方法及在我院的临床应用情况。澳大利亚生产的全自动锝气体发生器能生成一种核素显像剂—放射性锝气体,用于肺通气显像,诊断和鉴别诊断肺部疾病,特别是对肺栓塞的诊断具有重要的应用价值。该气体具有生成及检测简便、价格便宜、制备快速准确、使用安全、成像效果佳等特点。结果表明,此仪器产生的一种新型肺通气显像剂与其同类型显像剂相比,其灵敏度和特异性高,重复性和准确性好,对于鉴别诊断肺部疾病具有独到的优点。
Technetium gas preparation methods and clinical application in our hospital. The automatic technetium gas generator produced in Australia can generate a radionuclide technetium - radioactive technetium gas for lung ventilation imaging, diagnosis and differential diagnosis of pulmonary diseases, especially for the diagnosis of pulmonary embolism . The gas has the advantages of simple generation and detection, low price, fast and accurate preparation, safe use and good imaging effect. The results show that this instrument produces a new lung imaging contrast agent compared with its imaging agent, its sensitivity and specificity, repeatability and accuracy, for the differential diagnosis of lung disease has unique advantages.
