自从~(131)碘和~(99)m锝应用于临床以来,甲状腺扫描已成为诊断甲状腺肿物的常规方法之一,其临床价值已得到充分肯定。但用~(131)碘(或~(99m)锝)示踪作甲状腺扫描主要反映甲状腺结节的位置、大小、功能状态和形态上的异常,对良恶性病变的鉴别有一定限度。实践证明,~(131)碘(或~(99)m锝)扫描为冷结节则提示有癌变的可能,国外文献报道认为单个冷结节癌变的发生率为15％～58％。国内文
Since the application of ~(131) iodine and ~(99) m 锝 to the clinic, thyroid scanning has become one of the routine methods for the diagnosis of thyroid mass. Its clinical value has been fully affirmed. However, the use of ~(131) iodine (or ~(99m) 示) tracer for thyroid scanning mainly reflects the location, size, functional status, and morphological abnormalities of thyroid nodules. There are certain limits to the differentiation of benign and malignant lesions. Practice has shown that ~(131) iodine (or ~(99)m锝) scans are cold nodules suggesting the possibility of cancerous, foreign literature reported that the incidence of single cold nodules cancerous rate was 15% to 58%.
