二维超声与弹性成像技术在甲状腺癌诊断中的价值

The Value of Two-Dimensional Ultrasound and Elastography in the Diagnosis of Thyroid Carcinoma

目的探讨二维超声与弹性成像技术在甲状腺癌诊断中的价值。方法收集近3年我院诊断为甲状腺癌的患者,共159例,患者平均年龄(49.6±13.7)岁,男性79例,女性80例,发现病灶240处,所有患者入院后行常规二维超声和弹性成像检测。以术后病理诊断为金标准,对比常规二维超声与二维超声联合弹性成像诊断甲状腺恶性肿瘤的正确率。结果 1病灶平均大小为(4.8±2.6)mm,左侧病灶135处,右侧病灶105处。肿瘤病理为甲状腺乳头状癌180个、滤泡型癌36个及髓样癌24个。2常规二维超声与二维超声联合弹性成像诊断甲状腺恶性肿瘤的正确率分别为70%、84.6%,差异有统计学意义(P<0.05)。结论相对于单纯使用二维超声诊断甲状腺癌,本次研究认为二维超声联合弹性成像可以提高甲状腺癌的诊断正确率。

Objective To discuss the value of two-dimensional ultrasound and elastography in the diagnosis of thyroid carcinoma. Methods To collect the patients who diagnosed hyroid carcinoma in our hospital nearly 3 years, a total of 159 cases, average age is（49.6±13.7）years old, male 79 cases, female 80 cases, to find the lesions is 240. All patients were given conventional two-dimensional ultrasound and elastography detection, postoperative pathological diagnosis as the gold standard, to compare the correct rate of conventional two-dimensional ultrasound and elastography in the diagnosis of thyroid malignant tumor. Results The average size of lesion is（4.8±2.6）mm, the left lesions is 135, 105 lesions located in the right. The tumor pathology is 180 cases of thyroid papillary carcinoma, 36 cases of follicular carcinomas and 24 cases of medullary carcinoma. The correct rate of conventional two-dimensional ultrasound and two-dimensional ultrasound combined with elastography were respectively 70% and 84.6%, differences has statistical significance（p〈0.05）. Conclusion This study considers that two-dimensional ultrasound combined with elastography can improve the accuracy of diagnosis of thyroid carcinoma compared with only using two-dimensional ultrasound in diagnosis of thyroid carcinoma.
