超声造影和弹性成像对不同大小甲状腺乳头状癌检出敏感性的探讨

Analysis on sensitivity of contrast-enhanced ultrasound and ultrasonic elastography in detecting different sizes of thyroid papillary carcinoma

目的探讨超声造影和弹性成像对不同大小甲状腺乳头状癌的检出敏感性。方法对64例甲状腺乳头状癌行超声造影和弹性成像检查，将结节按直径大小分为两组（≤1cm组和〉1cm组），观察两种方法在不同组中的特征，并对比分析两种方法在不同组中的检出敏感性。结果总体比较显示，超声造影检出敏感性高于弹性成像，两者差异有统计学意义。分组比较显示，≤1cm组中造影与弹性的检出敏感性无明显差异，两者均具较高检出价值；〉1cm组中超声造影检出敏感性优于弹性成像，差异具有统计学意义。结论超声造影和弹性成像对甲状腺乳头状癌的检出均有较高的价值，在〉1cm的甲状腺乳头状癌诊断中造影的检出敏感性高于弹性成像。

Objective To explore the sensitivity of contrast-enhanced ultrasound （CEUS） and ultrasonic elastography（UE） in detecting different sizes of thyroid papillary carcinoma. Methods 64 cases of thyroid papillary carcinoma were divided into two groups according to the diameter size（group 1, ≤ 1 cm; group 2, 〉 1 cm） and examined by the contrast-enhanced ultrasound and elastography, then the features were analyzed and the sensitivity for detecting of the two methods in different groups were compared. Results The sensitivity for detecting in CEUS was higher than in UE, which had significant difference between two methods. CEUS and UE were valuable for detecting and they had no difference in sensitivity for detecting in group 1. There was a significant difference in sensitivity for detecting between two methods in group 2. Conclusions Both CEUS and UE were valuable in diagnosis of thyroid papillary carcinoma and the sensitivity for detecting in CEUS is higher than in UE in group 2.
