摘要
目的:探讨甲状腺良恶性结节超声造影特征及定量参数与病理微血管密度(MVD)的相关性,为甲状腺良恶性结节的不同灌注特点提供病理依据。方法:回顾性分析122例甲状腺结节的超声造影表现,进行时间-强度曲线(TIC)分析。对术后标本行免疫组化CD31、CD34染色后计数MVD,对甲状腺结节超声造影定量参数与MVD计数进行相关性分析。结果:在超声造影增强达峰时,甲状腺癌多表现为不均匀低增强,结节性甲状腺肿多表现为等增强,腺瘤表现为高增强。甲状腺癌组IMAX、MVD均低于结节性甲状腺肿及腺瘤组,差异均具有统计学意义(P<0.05)。甲状腺结节超声造影定量参数中IMAX与MVD呈显著正相关(rCD31=0.814,PCD31<0.01;rCD34=0.803,PCD34<0.01)。结论:低增强是诊断甲状腺癌重要的增强模式,甲状腺癌呈乏血供状态。
Abstract
Objective: To investigate the performance of thyroid nodules with contrast-enhanced ultrasound(CEUS) and the correlation between CEUS quantitative parameters and microvessel density(MVD), to provide pathologic basis for different perfusion characteristics of benign and malignant thyroid nodules. Methods: The CEUS features of 122 patients with thyroid nodules were retrospectively analyzed. The time-intensity curves(TIC) were analyzed by TomTec software. Immunohistochemical staining were performed to evaluate the MVD in the surgical specimens, and the correlation of quantitative parameters with MVD were assessed. Results: When the ultrasound contrast enhancement to the peak, the thyroid carcinoma showed homogeneous hypo-enhancement, nodular goiter showed iso-enhancement, thyroid adenoma showed hyper-enhancement. IMAX and MVD of thyroid carcinoma were lower than nodular goiter and thyroid adenoma, and the differences were statistically significant(P<0.05). A positive correlation existed between the IMAX and MVD(rCD31=0.814,PCD31<0.01; rCD34=0.803, PCD34<0.01). Conclusions: Hypo-enhancement was the important CEUS enhancement patterns to diagnose thyroid carcinoma, thyroid carcinoma was lack of blood supply.
