超声检查对甲状腺微小乳头状癌的诊断价值

目的探讨术前超声检查对甲状腺微小乳头状癌（PTMC）的诊断价值。方法选取本院2013年1月~2013年12月收治的PTMC患者69例经手术和病理证实的共78个PTMC病灶超声图像,与同期随机选取的50个良性结节声像图进行对照。结果 69例PTMC患者与病理诊断相符的有56例,相符率为81.16%（56/69）,误诊率为10.14%（7/69）,漏诊率为8.70%（6/69）;78个PTMC结节的直径超声检测值为（10.56±8.35）mm,病理镜检测值为（3.95±1.23）mm,超声检测值与病理镜检测值比较,差异有统计学意义（t=5.551,P=0.000）;78个超声诊断的PTMC结节在形态、边界、纵横比〉1等方面与50个良性节比较,差异有统计学意义（P〈0.05）。结论超声检查对PTMC虽然具有一定的缺陷,但其临床应用价值仍然较大。

The diagnostic value of ultrasound examination in papillary thyroid mi- crocarcinoma

Objective To explore the diagnostic value of preoperative ultrasound examination for papillary thyroid mi- crocarcinoma （PTMC）. Methods Ultrasound image of 78 lesions confirmed by operation and pathology of PTMC in 69 cases with PTMC from January to December 2013 in our hospital were selected,and they were compared with the sono- gram 50 benign nodules selected randomly. Results Among 69 patients with PTMC,there were 56 cases matching with the pathological diagnosis,the coincidence rate was 81.16% （56/69）,the misdiagnosis rate was 10.14% （7/69）,the missed diagnosis rate was 8.70% （6/69）;diameter of 78 PTMC nodule in ultrasonic testing was （10.56 ±8.35）mm,the value of pathological mirror detection was （3.95±1.23）mm,and there was a statistical difference of detection value between the two groups （t=5.551 ,P=0.000）;78 ultrasonic diagnosis of PTMC nodules in shape,boundaries,the aspect ratio （more than 1） etc were significantly different with the 50 benign nodules （P〈0.05）. Conclusion Ultrasound examination of PTMC has some shortcomings,but its value of clinical application is stil bigger.
