一、前言核医学显象检查是把γ射线核素标记的放射性药物作为示踪剂,通过体外测定体内分布及其各时期的变化,以显像表示的一种检查。自1955年由Taplin等引入~(131)I-玫瑰红(RB)以来,主要是以肝外胆道阻塞诊断为目的而进行的检查。测定装置的主体从闪烁扫描机变成闪烁照相,所使用的放射性核素也从~(131)I向~(99m)Tc变迁,而且~(123)I、~(97)Ru等也正被试用。现在在使用许多标记化合物的同时,主要是推动制备更好的放射药物的新产品。这是因为现在使用的药物还有各种缺点。本文主要想从放射性核素和标记化合物方
I. Introduction Nuclear medicine imaging examination is a radioactive drug labeled with γ-ray radionuclide as a tracer, in vivo determination of in vivo distribution and changes in each period, to show that a test. Since the introduction of ~ (131) I-Rose Bengal (RB) by Taplin et al in 1955, it has been mainly based on the diagnosis of extrahepatic biliary obstruction. The main body of the measuring apparatus changes from a scintillation scanner to a scintilloscope, and the radionuclides used also change from ~ (131) I to ~ (99m) Tc, and ~ (123) I, ~ try out. At the same time as many of the labeled compounds are being used, new products are mainly being promoted to make better radiopharmaceuticals. This is because there are various disadvantages to the drugs currently used. This article mainly from radionuclides and labeled compounds side
