鉴别持久存在的新生儿黄疸,往往很困难。常规的生化试验不能鉴别新生儿结合型或混合型高胆红素血症的原因。曾利用放射性~(13)(?)碘标记的玫瑰红作经粪便排出量的测定或系列腹部影象检查,作为鉴别方法,但其结果不能令人满意。在临床应用上,~(99m)锝的原子核性质比~(131)碘为优越。~(99m)锝的优点为半衰期短(6小时),纯γ射线,所显示的图像清晰,而且患 Identification of persistent neonatal jaundice is often difficult. Conventional biochemical tests fail to identify the causes of neonatal conjunctival or mixed hyperbilirubinemia. Had used radioactive (13) (?) Iodine-labeled rose red for the determination of fecal output or series of abdominal imaging examination as a method of identification, but the results are unsatisfactory. In clinical applications, ~ (99m) technetium nucleus than ~ (131) iodine is superior. The advantage of ~ (99m) technetium is its short half-life (6 hours), pure gamma-rays, clear images displayed, and
