目的探讨超声引导下经皮穿刺热消融治疗甲状腺良性结节的临床效果及安全性。
Objective To investigate the clinical effectiveness and safety of ultrasound-guided percutaneous thermotherapy for benign thyroid nodules.
方法：回顾总结1995年1月至2002年7月间678例甲状腺良性结节手术的临术资料。
Method Review the clinical data of 678cases of surgical operation to benign thyroid nodules from Jan1995to Jul 2002was summed up.
老年人甲状腺结节绝大多数为良性，应以内科随访及治疗为主，手术则需谨慎。
The majority of the elderly for benign thyroid nodules should be based medicine and follow-up, and the surgery should be cautious.
多数甲状腺结节为良性。甲状腺癌一般也非极度恶性，如果治疗得当，患者可以达到正常寿命。
Most thyroid nodules are benign, and thyroid cancers generally are not highly malignant and are compatible with normal life expectancy if treated properly.
CT对甲状腺癌的诊断与病理诊断符合率86%，对良性结节的诊断符合率为90%。
The diagnosis coincidence of CT to thyroid cancer nodules is 86% or so, to benign nodules is 90% or so.
结果甲状腺恶性结节弹性成像硬度评分高于良性结节，恶性结节弹性成像图与灰阶声像图的面积比值高于良性病灶（P均<0.05）。
Results The elastographic scores and the area ratios of nodules on elastograms and on grey-scale images of malignant thyroid nodules were higher than those of benign ones (both P<0.05).
