Department of Ultrasound,Shaanxi Cancer Hospital,Shaanxi Xi?tn 710061,China. 【Abstract】0bjective:To explore the value of contrast—enhanced ultrasound(CEUS)in the diagnosis of papillary
thyroid carcinoma(PTC).Methods:Fifty one cases were included in this study.All the PTC lesions underwent exam— inations of CEUS.The type of time—intensity curves(TIC)was analyzed by TomTec software.Results:A1l PTC
showed perfusion defects was a touch weak imaging(P<0.001),non—uniform enhancement,increase time lesions
began later than the surrounding thyroid tissue(P<0.001),fade time showed no difference(P>0.05).Conclusion: Perfusion defects,faint weak and uneven increase of papillary thyroid carcinoma after contrast—enhanced ultrasound
can provide important supplement to diagnosis and may further improve the diagnostic accuracy for PTC. 【Key words】thyroid;papillary carcinomas;contrast—enhanced uhrasonography;diagnosis

【摘要】 目的:探讨超声造影(CEUS)诊断甲状腺乳头状癌(PTC)的可行性。方法:对51例超声疑似PTC的
患者,术前经灰阶及CDFI检查后行CEUS检查,动态观察微泡在病灶灌注的全过程、灌注模式及边缘灌注情
况。结果:PTC结节大小与超声造影表现有显著相关性(P<0.001),始增时间、峰值时间在正常甲状腺组织
与PTC组织有显著差异(P<0.001),但边缘增强和消退时问并无此发现(P>0.05)。结论:灌注缺损、淡淡弱
灌注及不均匀增强三种灌注模式在一定程度上提示FFC,较常规灰阶超声能更早、更敏感地评价FFC乏血供
灌注特征。 【关键词】超声造影;甲状腺;乳头状癌;诊断

灰阶超声和CDFI是评估甲状腺肿瘤首选的影像学方
法” J。但仍有30%一50%的微小结节性质不易判断。近
年来国内外学者应用第二代超声造影剂(SonoVue)来评价甲
状腺良恶性结节的报道日趋增多。CEUS是通过显示造影剂 微泡的运动、分布来了解感兴趣区域的血流灌注状态及血流
动力学变化,其准确率为74%一82% -5 3。CEUS评估甲状
腺良恶性肿瘤尚处于探索阶段 。 。本研究旨在探讨CEUS
诊断PTC的可行性。

1.1研究对象 选取2009年6月12日一2012年3月12日在我院行
CEUS并经病理证实的51例(个)PTC患者。男11例,女40
例;年龄18—58岁,平均年龄(45.8±1.2)岁。结节大小0.6
—3.7cm(平均1。7 cm),其中<1.0cm的结节21例,1.0
2.Ocm的结节23例,>2.0cm的结节7例 低回声伴微小
钙化、形态不规则、边界模糊、 横>1等征象 者被纳入
受试者,彩色血流模式分为3型:I型:无血流信号;1I型:结
节周边有星点状血流信号;111型:结节内血流信号丰富杂
乱 。51例患者均有知情同意书。
1.2仪器与造影剂
采用Philips iU22超声诊断仪,L9—3探头,选择仪器预
设甲状腺CEUS检查条件,机械指数(MI)0.06—0.08,增益
调至仅显示甲状腺被膜和颈总动脉。参数设定后保持不变。
造影剂使用博莱科(Bracco)公司生产的SonoVue微泡,使用
前将5ml生理盐水注入冻干粉末中,反复震荡形成白色SF6
混悬微泡。

【Abstract】 Objective:To evaluate the short—term efficacy and toxicity of nedaplatin and 5一fluorouracil induction
chemotherapy plus concurrent chemoradiotherapy(CCRT)in the treatment of locally advanced nasopharyngeal carci—
noma.Methods:Total 45 patients with locally advanced nasopharyngeal carcinoma were treated with 2 cycles of in—
duction chemotherapy with nedaplatin(80mg/m ,d1)and 5一fluorouracil(500mg/nl ,dl 5)followed by 3 cycles of
nedaplatin(80rag/m ,dl_22 43)and radiotherapy.Results:Of45 patients 42 patients completed induction chemothera—
PY and subsequent concurrent chemoI_adiotherapy and were evaluable for treatment response.The overall response rate
(ORR)in the primary site were 85.71%[complete response(CR)in 9.52%]and 100%[complete response(CR)
in 92.86%]respectively at completing induction chemotherapy and 3 months after concurrent chemoradiotherpy.In
involved nodal stations,the overall response rate were 88.57%[complete response(CR)in 11.43%]and 100%
[complete response(CR)in 97.1 4%]at completing induction chemotherapy and 3 months after chemoradiotherapy.
The main toxicity was neutropenia during induction chemotherapy.Oral mucositis,skin desquamation,neutropenia and
thrombocytopenia were the most common toxicities during chemoradiotherapy.There were no treatment—related deaths
during this study.Conclusion:Nedaplatin and 5一fluorouracil induction chemotharapy plus concurrent chemoradio—
therapy is effective and tolerable in the treatment of locally advanced nasopharyngeal carcinoma.Long—term thera—
peutie effects of this treatment need further observation. 【Key words】nasopharyngeal carcinoma;drug therapy;nedaplatin;radiotherapy
