超声对甲状腺癌和甲状腺腺瘤的诊断和鉴别诊断价值分析

The Diagnosis and Differential Diagnosis Value of Ultrasound for Thyroid Cancer and Thyroid Adenoma

目的:探讨超声对甲状腺癌和甲状腺腺瘤的诊断和鉴别诊断价值。方法:回顾性分析2012年1月-2013年1月在本院住院治疗的甲状腺癌30例,甲状腺腺瘤68例的超声资料,并进行鉴别诊断分析。结果:68例甲状腺腺瘤患者中共84个结节,30例甲状腺癌患者中共32个结节。30例甲状腺癌中包括滤泡性癌2例,低分化癌1例,乳头状癌26例,髓样癌1例。甲状腺腺瘤Vmax=(26.3±2.7)cm/s,RI=(0.53±0.28)。甲状腺癌Vmax=(50.8±3.1)cm/s,RI=(0.72±0.13),两组比较差异均有统计学意义(P<0.05)。结论:彩色超声具有简便,廉价,准确并重复性好的优点,能较为精确的显示甲状腺肿瘤的位置、形态、大小、回声及淋巴结情况,可以用于甲状腺腺瘤与甲状腺腺癌的诊断与鉴别诊断。

Objective： To investigate the diagnosis and differential diagnosis value of Ultrasound for thyroid cancer and thyroid adenoma. Method： A retrospective analysis of the ultrasound data included 10 cases of thyroid cancer, 68 cases of thyroid cancer from January 2012 to January 2013 in the hospital, and the differential diagnosis were analyzed. Result： Sixty- eight cases of thyroid adenoma had 84 nodules, 30 cases of thyroid cancer included 2 cases of follicular carcinoma, 1 poorly differentiated carcinoma, 26 cases papillary carcinoma, 1 medullary carcinoma. Thyroid adenoma Vmax= （ 26.3 ± 2.7 ） cm/s, RI= （ 0.53 ± 0.28 ） . Thyroid cancer Vmax= （ 50.8 ± 3.1 ） cm/s, RI= （ 0.72 ±0.13 ）, and the differences between the two groups were statistically significant （P〈0.05） . Conclusion： Color Doppler ultrasound is a simple, inexpensive, accurate methods, can accurate display of thyroid tumor＇ location, shape, size, echo and lymph nodes, thus improve the diagnosis rate of thyroid tumors, can be used for diagnosis and differential diagnosis of thyroid adenoma and thyroid carcinoma.
