【摘要】：目的探讨二维超声联合CEUS对良恶性甲状腺结节的鉴别诊断价值。方法对94例甲状腺结节患者(共99个结节)行常规超声、CEUS检查,观察甲状腺结节的二维超声、CEUS特征。分析比较良、恶性甲状腺病变超声特征的差异。对存在统计学意义的观察指标进行赋值后、比较各分值的鉴别诊断效能。结果 99个甲状腺结节中,30个为恶性结节,69个为良性结节。良、恶性病灶二维声像图特征中,回声、纵横比、形态、边界、钙化、回声均匀度的差异均有统计学意义(P均0.05);CEUS特征中,相对始入时间、环状增强、后期低增强的差异均有统计学意义(P均0.05)。二维超声与CEUS参数的总评分≥4分时,可获得较好的敏感度及特异度、分别为86.67%(26/30)、78.26%(54/69)。结论二维超声联合CEUS是鉴别诊断甲状腺结节良、恶性的一种可行、有效的方法。
[Abstract]:Objective to evaluate the value of two-dimensional ultrasound combined with CEUS in differential diagnosis of benign and malignant thyroid nodules. Methods 94 patients with thyroid nodules (99 nodules) were examined by conventional CEUs. The ultrasonographic characteristics of benign and malignant thyroid lesions were analyzed and compared. The differential diagnostic efficacy of each score was compared after the evaluation of the observed indexes with statistical significance. Results of 99 thyroid nodules, 30 were malignant and 69 were benign. The differences of echo, aspect ratio, shape, boundary, calcification and echo uniformity in the two dimensional sonographic features of benign and malignant lesions were statistically significant (P < 0.05). The difference of low enhancement was statistically significant (P < 0.05). When the total score of 2-D ultrasound and CEUS parameter is 鈮，
