一、短碘(~(132)Ⅰ)对大鼠远期影响单一短碘对生物远期影响的观察Ⅰ国外尚未见报告。有些核医学专家试图用短半衰期的放射性同位素(如~(132)Ⅰ、T2.28小时)代替~(131)I在临床上使用,以避免用~(131)I后远期出现甲状腺功能低下和发生甲状腺肿瘤。认为半衰期短、放射性在体内消失快,对病人辐射剂量可大为减少(尤其是低能的短半衰期的同位素)。这样可提高使用的放射性强度,求得较好的放射性测量结果,使之诊断更加准确,治疗效果更
First, the short-term iodine (~ (132) Ⅰ) the long-term effects of a single short-term observation of short-term biological effects of long-term biological I have not been reported abroad. Some nuclear medicine experts try to use the short half-life of radioisotopes (such as ~ (132) Ⅰ, T2.28 hours) in place of ~ (131) I in the clinical use, to avoid the use of ~ (131) I hypothyroidism after long-term And the occurrence of thyroid tumors. The short half-life, the rapid disappearance of radioactivity in the body, and the greatly reduced radiation dose to patients (especially the short half-life isotopes of low energy) are considered. This can increase the use of radioactive intensity, to obtain better radioactivity measurement, so that the diagnosis is more accurate, the treatment effect is more
