【摘要】 目的探讨桥本甲状腺炎(HT)的二维及彩色多普勒超声声像图特征及临床诊断价值。方法对207例患者其中包括HT(HT组)80例、亚急性甲状腺炎(SAT组)60例、结节性甲状腺肿大组46例、甲状腺腺瘤组11例、甲状腺乳头状癌组10例及正常对照组50例应用二维及彩色多普勒超声检查,分析其声像图特征及鉴别要点。统计分析指标包括病灶的数目、性质、钙化特征、回声特征及血流情况,并对各组患者间指标进行多样本率比较(卡方检验)。并对桥本甲状腺炎、亚急性甲状腺炎及正常对照组的甲状腺形态改变特征进行统计分析,主要统计指标为左叶、右叶及峡部厚度变化。结果桥本甲状腺炎与亚急性甲状腺炎的形态改变与正常对照组比较差异有统计学意义(P<0.05)。桥本甲状腺炎病例组与亚急性甲状腺炎之间比较,指标差异均无统计学意义(P>0.05)。其余各组与桥本甲状腺炎病例组间的数目及钙化指标差异有统计学统计学意义(P<0.05),而血流及性质差异无统计学意义(P>0.05)。与其他甲状腺疾病比较,桥本甲状腺炎超声图特征包括呈不规则强回声带,结节呈实质性为主,可以钙化,且病灶血流信号丰富,另外常见峡部增厚,但此特征与亚急性甲状腺炎差异无统计学意义(P>0.05)。结论二维及彩色多普勒超声对桥本甲状腺炎的诊断有一定特异性,对临床诊断及治疗有重要的意义。更多还原

【Abstract】 Objective To investigate the diagnostic value of 2-dimensional and color Doppler for Hashimoto’s thyroiditis(HT) and the characteristics of Doppler ultrasound sonography.Methods 207 patients including 80 cases of HT,60 cases of subacute thyroiditis(SAT),46 cases of nodular goiter,11 cases of thyroid adenoma, 10 cases of thyroid papillary carcinoma,50 healthy subjects were examined by two-dimensional and color Doppler flow imaging.The characters of Doppler ultrasound sonography and highlight of appreciation were analyzed. The parameters including focal number,character,calcify character,resonance and BF were statistically analyzed.The appearance differences between HT and SAT including thickness of left lobe,right one and isthmic portion were observed.Results There were significant differences in appearance difference between HT and healthysbujects(P<0.05).But there was no significant difference between HT and SAT,and there were significant differences in calcify and number between HT group and other groups(P<0.05),but no significant differences were found in BF and characters.The characters of ultrasonogram in HT including anomalism echo zone,parenchymatous nodus,calcif and abundanceBF and the increase of isthmic portion thickness were found, but there were no significant differences between HT and SAT.Conclusion Ultrasonography has many advantages in diagnosing Hashimoto’s Thyroiditis.更多还原
