1 育龄、妊娠、哺乳期妇女核医学检查可能受到的影响核医学检查包括体内和体外两种方法。后者主要指放免分析,受检者不受射线照射。体内诊断方法主要是影像诊断,国内主要设备是SPECT,约250台左右,每年受检人数在百万人次以上,其中育龄、妊娠、哺乳期妇女约占10％左右。SPECT所应用到的放射性药物90％以上是锝标记物(半衰期为6.02小时,单一纯γ射线,能量140Kev),少部分是~(131)Ⅰ(半衰期为8.04天,81％为γ射线,能量是364Kev)及~(201)TL半衰期
1 child-bearing, pregnancy, breast-feeding women may be affected by nuclear medicine nuclear medicine tests, including both in vitro and in vivo methods. The latter refers to the release analysis, the subjects were not exposed to radiation. In vivo diagnostic methods are mainly diagnostic imaging, the major domestic equipment is SPECT, about 250 units, the number of people in each year in more than 1 million, of which child-bearing age, pregnancy, lactation accounts for about 10%. More than 90% of radiopharmaceuticals used in SPECT are technetium markers (half-life of 6.02 hours, single pure gamma-ray, energy 140 Kev) and a small proportion of 131 I (half-life of 8.04 days, 81% of gamma rays, energy Is 364 Kev) and ~ (201) TL half-life
