为了辅助静脉栓塞和肺栓塞的诊断,在最近20～30年里已创立了多种放射性同位素的诊断方法。在这些新的同位素诊断方法中,除了~(125)I纤维蛋白原吸收试验,其它方法直到近5年才开始采用一种可以接受的标准进行精确的对比研究。本文第一部分介绍了放射性同位素在诊断静脉血栓时的应用。第二部分介绍放射性同位素在诊断肺栓塞时的应用。 To assist in the diagnosis of venous thromboembolism and pulmonary embolism, several diagnostic methods for radioisotopes have been established in the recent 20 to 30 years. In these new isotope diagnostic methods, except for the ~ (125) I fibrinogen absorption test, other methods did not begin an exact comparative study using an acceptable standard until almost five years ago. The first part of this article describes the use of radioisotopes in the diagnosis of venous thrombosis. The second part introduces the application of radioisotopes in the diagnosis of pulmonary embolism.
