常规超声及超声造影诊断甲状腺微小乳头状癌的价值

The Value of Conventional Ultrasound and Contrast - enhanced Ultrasound in the Diagnosis of Papillary Thyroid Microcarcinoma

目的探讨常规超声及超声造影在甲状腺微小乳头状癌中的价值。方法收集2014年3月-2015年3月我院甲状腺结节的患者，根据术后病理诊断，分为50例观察组（病理结果为恶性结节）和50例对照组（病理结果为良性结节）。结果①观察组结节直径和对照组结节直径差异有统计学意义（P〈0．05）；②两组常规超声检查（形态、边界、纵横比、微钙化、异常淋巴结）结果比较差异具有统计学意义（P〈0．05）；③两组超声造影结果（增强时间、增强方式、增强强度、边界是否清晰、环状增强、增强后结节大小）结果比较差异具有统计学意义（P〈0．05）。结论常规超声及超声造影在甲状腺微小乳头状癌的诊断中有较高价值，两组联合使用可以提高诊断准确率。

Objective To investigate the value of conventional ultrasound and contrast - enhanced ultrasound （CEUS） in papillary thyroid microcarcinoma. Methods Patients with thyroid nodules were collected from Mar. 2014 to Mar. 2015 in our hospital. Patients were divided into observation group （malignant nodules, n = 50 ）and control group （ benign nodules, n = 50） according to pathological results. Results ①There was significant difference in diam- eter of nodules between observation group and control group （P 〈 0. 05 ） ;②There were significant differences in con- ventional ultrasonography results （ morphology, boundary, aspect ratio, microcalcification and abnormal lymph nodes ） between the two groups （ P 〈 0.05 ） ; ③There were significant differences in contrast - enhanced uhrasonography resuits（ enhancement time, enhancement mode, enhancement intensity, boundary, annular enhancement and enhanced nodule size）between the two groups（P 〈 0.05 ）. Conclusion Conventional ultrasound and contrast -enhanced ultrasound have good value in the diagnosis of papillary thyroid microcarcinoma. The combination of these can improve the diagnostic accuracy.
