摘　　要：目的探讨超声造影对弥漫背景下甲状腺结节良恶性评价的临床价值。方法回顾性纳入行超声造影检查的甲状腺弥漫性病变伴结节的患者50例(55个结节),分析其超声造影灌注方式。结节性质由组织或细胞病理学结果确定。结果弥漫性病变背景下的甲状腺结节超声造影灌注模式分为5种,其中低灌注,边界分明者诊断良性结节特异度为100%,而不均匀低灌注及向心性低灌注诊断恶性结节特异度为86.7%。结论超声造影对弥漫性背景下甲状腺结节临床诊断提供重要信息。Objective The aim of this study was to discuss the clinical value of contrast-enhanced ultrasound （CEUS） for benign and malignant thyroid nodules with diffuse disease. Methods Fifty patients with 55 thyroid nod-ules and diffuse disease underwent CEUS examination in our department. We retrospectively analyzed the characteristics of perfusion enhancement. The final diagnosis was determined by pathological or cytological results. Results Under the background of diffuse disease, characteristics of CEUS perfusion were divided into 5 categories. Among them, low perfusion with the sharp edge had the specificity of 100% for the diagnosis of benign nodules, while uneven,low perfusion and centrality infusion had the specificity of 86.7% for the diagnosis of malignant nodules. Conclusions CEUS supply important information for diagnosis of thyroid nodules with diffuse disease.
