孤立性甲状腺结节放射性核素扫描的主要目的是鉴别病变的良恶性。目前普遍认为。孤立的无功能结节和多发性结节中的显著无功能结节,癌的发生率高于单纯的多发性结节。某些结节临床上检查认为是孤立性的,可手术证实确是多发性;功能亢进的甲状腺结节几乎没有恶性的。因此,临床上对甲状腺孤立性结节和多发性结节中显著无功能结节特别注意!甲状腺结节中有15%是囊性的,且大多数为良性,原发性甲状腺癌仅占1～2%;实质性无功能结节恶性率约为20%,一旦发现,即应手术。可见,鉴别结节是囊性或实质性十分重要。

The main purpose of radionuclide scanning for isolated thyroid nodules is to identify the benign and malignant lesions. It is generally believed. Isolated non-functional nodules and significant no-function nodules in multiple nodules had a higher incidence of cancer than simple multiple nodules. Some of the nodules were clinically considered as isolated and confirmed by surgery to be multiple; the hyperthyroid thyroid nodules were almost non-malignant. Therefore, clinically noteworthy attention is paid to significant no-function nodules in solitary nodules and multiple nodules in the thyroid gland. 15% of thyroid nodules are cystic and mostly benign. Primary thyroid cancer accounts for only 1 ～2%; Substantially no-function nodules The malignant rate is approximately 20%. Once discovered, surgery should be performed. Obviously, it is very important to identify nodules as cystic or substantive.
