目的探讨实时超声造影技术对甲状腺微小乳头状癌(PTMC)的诊断价值.方法对143例患有甲状腺结节(最大直径≤1.0 cm)且无弥漫性病变的患者,共149个结节,于术前行超声造影检查,并与手术病理结果进行对照分析.结果 149个甲状腺结节,良性75个,微小乳头状癌74个,最大直径0.5～1.0 cm的甲状腺微小乳头状癌超声造影多表现为不均匀增强,与良性结节对比差异有统计学意义(W=1 029.5,Z=-5.524,P=0.000);最大直径＜0.5 cm的甲状腺微小乳头状癌超声造影多表现为均匀增强,与良性结节对比差异无统计学意义(W=933.0,Z=-1.738,P=0.082).结论超声造影在最大直径0.5～1.0cm甲状腺微小乳头状癌的诊断中具有重要价值.

Objective To explore the imaging features of papillary thyroid microcarcinoma(PTMC) with real time contrast-enhanced ultrasound.Methods One hundredand forty-three cases with 149 thyroid nodules(no diffuse lession) were divided into two groups according to the diameter size(group 1,＜0.5 cm;group 2,0.5-1.0 cm) and examined by contrast-enhanced ultrasound during preoperation.Pathology was followed up as golden diagnosis criteria.Results Seventy-five benign tumors and 74 PTMC were confirmed by pathology.There were significant differences in echoes homogeneity between benign and malignant tumors in group 2(W =1 029.5,Z =-5.524,P =0.000) but no in group 1(W =933.0,Z =-1.738,P =0.082).And nonhomogeneous enhancement were showed in most PTMC in group 2.But most PTMC showed homogeneous enhancement in group 1.Conclusions Contrast-enhanced ultrasound is valuable in diagnosis of PTMC with the diameter size of 0.5-1.0 cm.
