甲状腺扫描是放射性同位素应用于临床脏器显影最早的方法之一,目前已成为了解甲状腺位置、形态、大小和临床区分甲状腺结节类型、搜索甲状腺癌转移灶的常规方法。 甲状腺显影剂的品种繁多,一般可以分成碘的放射性同位素及~(99m)Tc两大类。国外文献报导~(123)I作为甲状腺扫描剂有其一系列的优点。本文比较~(123)I、~(99m)Tc和~(131)I对甲状腺结节的扫描结果,初步探讨其优缺点。
Thyroid scan is one of the earliest methods of radioisotope application in clinical organ development. Nowadays, thyroid scan has become a routine method to search thyroid gland location, shape, size and clinical classification of thyroid nodules and to search for metastatic thyroid cancer. Thyroid developers a wide variety, generally can be divided into iodine radioisotopes and ~ (99m) Tc two categories. Foreign literature reported ~ (123) I as a thyroid scan has a series of advantages. In this paper, the results of ~ (123) I, ~ (99m) Tc and ~ (131) I on thyroid nodules were compared and their advantages and disadvantages were discussed.
