甲状腺结节是指甲状腺细胞在局部异常生长所引起的散在病变。一般人群中通过触诊的检出率为3%-7%,借助高分辨率超声的检出率可高达20%-76%。大约有5%-15%的甲状腺结节为恶性,即甲状腺癌。目前认为发现甲状腺结节最好的方法是甲状腺B超。既方便,也没有辐射等不良的影响。既可看形态,还可看血流。其他的检查如CT/MRI,只有在肿瘤与周围关系不清楚时才选择。
Thyroid nodules are scattered lesions caused by abnormal growth of thyroid cells. The detection rate of the general population by palpation is 3% -7%, with the detection rate of high-resolution ultrasound can be as high as 20% -76%. About 5% -15% of thyroid nodules are malignant, that is, thyroid cancer. Now that the best way to find thyroid nodules is thyroid B ultrasound. It is convenient and has no adverse effects such as radiation. Can look at the form, but also look at the blood flow. Other tests, such as CT / MRI, are only available if the relationship between the tumor and the surrounding area is unclear.
