摘　　要：目的探讨甲状腺微小占位性病变的超声造影表现。方法对70例病灶直径<10 mm的甲状腺占位性病变患者行超声造影检查,分析超声造影增强模式和时间-强度曲线。结果 61个结节性甲状腺肿以等增强、同进同退为主,环形增强较多;17个甲状腺腺瘤以高增强、快进慢退为主;15个甲状腺乳头状癌以低增强、环形增强为主,同进快退模式较多。甲状腺腺瘤造影剂到达时间与正常甲状腺组织比较差异有统计学意义(t=-4.007,P<0.05);甲状腺腺瘤和甲状腺乳头状癌的造影剂达峰时间与正常甲状腺组织比较差异均有统计学意义(t=8.331、-3.775,均P<0.05);甲状腺腺瘤的造影剂峰值强度与正常甲状腺组织比较差异有统计学意义(t=5.164,P<0.05)。结论超声造影对病变血供的敏感性较好,对诊断甲状腺微小占位性病变有一定价值,能为临床诊断提供有力的影像学依据。Objective To explore the contrast-enhanced ultrasonic manifestations of thyroid minimal tumor.Methods Seventy patients with thyroid occupying lesions of diameter 10 mm underwent contrast-enhanced ultrasonography,the contrast enhancement patterns and time-intensity curve was analyzed.Results Sixty-one thyroid nodules mainly in equal enhancement pattern,the same time in and out,ring enhancement more. 17 thyroid adenomas mainly in high enhancement pattern,fast-in and slow-out.15 thyroid papillary carcinomas mainly in low enhancement pattern,ring enhancement, equal-in and fast-out more. There were significant differences in the arrival time between thyroid adenoma and normal thyroid tissue（t =-4. 007,P〈0. 05）. The time to peak of thyroid adenoma and papillary thyroid carcinoma was significant different from that of normal thyroid tissue（t=8.331,-3.775,P〈0.05）.The peak intensity of thyroid adenoma was different from that of normal thyroid tissue（t=5.164,P〈0.05）.Conclusion The sensitivity of contrast-enhanced ultrasound to the blood supply of the lesion is good,it has certain value in diagnosis of minimum space occupying lesion of thyroid gland,and it can provide a strong imaging evidence for clinical diagnosis..
