摘要
目的探讨超声造影对甲状腺乳头状癌的诊断意义。方法对22例甲状腺乳头状癌通过时间-强度曲线(TIC)进行分析,比较肿块及周围正常腺体及不同结节间造影剂到达时间(AT),达峰时间(TTP),峰值强度(PI)参数的差别。结果22例肿瘤与临近甲状腺实质比较均呈高增强;18例表现为结节早于周围实质开始增强及消退,2例同进同出,2例同进慢出。结论超声造影技术可以为鉴别甲状腺乳头状癌提供更多有效的定量分析。
Objective To investigate the contrast enhanced ultrasonography by analyzing the sonographic characteristics of thyroid papillary carcinoma after injection sonovue.Methods Time-intensity curve in 22 cases with thyroid papillary carcinoma was analysed, and arrival time(AT), time to peak(TTP) and peak intensity(PT) in tumor were compared with those in normal gland and different nodules.Results 18 cases showed early wash in an early wash out in comparison with the adjacent thyroid parenchyma, 2 cases showed sam...
