放射性核素显像鉴别甲状腺"冷结节"良恶性的研究进展

甲状腺"冷结节"是甲状腺结节核素显像较为常见的表现形式,炎症、囊肿、肿瘤、出血等均可表现为冷结节,另外,据统计,平均约20%的甲状腺冷结节为甲状腺癌,因此准确鉴别甲状腺冷结节的性质不仅有助于全面检出甲状腺癌,而且可为临床选择正确治疗方案提供重要指导.目前,临床上依据显像剂的不同研究了多种鉴别甲状腺冷结节性质的方法,并且在不断完善中.

Study progress of nuclide imaging in the differential diagnosis of nonfunctional cold thyroid nodules

"Cold nodules" are the common form of thyroid nodules in radionuclide imaging. Inflammation, cysts, tumors, hemorrhage and so on can be expressed as cold nodules. And, according to the statistics, an average of about 20% of the cold nodules are malignant. So accurate identification of nonfunctioning thyroid nodules not only contribute to the comprehensive nature of the detection of thyroid cancer, but also the right choice for the clinical treatment programs provide an important guide. At present,on the basis of kinds of different imaging agents, a number of methods to identify the nature of thyroid cold nodules were developed, and constantly perfected.
