放射性核素显像(Radionuclides Imaging)以下简称(RI),是核医学诊断方法之一。我国目前已逐渐开始广泛应用,它是操作简单、检出率高、无创伤性的先进诊断方法。故将其概念、显像工具性能、疾病诊断机理及临床意义作一概述。 RI概念及显像工具性能 RI是利用放射性核素标记药物或化合物参与体内代谢过程,并通过其选择性的浓集在某脏器或病变处,然后以扫描机进行扫描或以γ照像机连续摄影,即可得某脏器及其病变的图像。 Radionuclides Imaging (hereinafter referred to as RI), is one of the nuclear medicine diagnostic methods. At present, China has gradually begun to be widely used, which is an advanced diagnostic method with simple operation, high detection rate and non-invasiveness. Therefore, the concept, imaging tool performance, disease diagnosis and clinical significance of a summary. RI concept and imaging tool performance RI is the use of radionuclide labeled drugs or compounds involved in metabolic processes, and through its selective concentration in an organ or lesion, and then scanned with a scanner or gamma camera Continuous photography, you can get some organs and lesions of the image.
