目的探讨彩超联合CT检查在甲状腺乳头状癌颈淋巴结转移中的诊断价值。方法 112例甲状腺乳头状癌患者,术前行彩超和CT检查,以病理检查结果为准评价彩超、CT、彩超联合CT的检查结果。结果术后病理证实颈淋巴结转移92例(82.1%),无颈淋巴结转移20例(17.9%);彩超、CT、彩超联合CT阳性预测值比较差异无统计学意义(P>0.05);彩超、彩超联合CT阴性预测值和诊断准确率明显高于CT,差异有统计学意义(P<0.05)。结论术前彩超联合CT对甲状腺乳头状癌颈淋巴结转移的诊断准确率高于单纯CT,为临床手术选择提供重要参考。
Objective To investigate the diagnostic value of color Doppler ultrasonography combined with CT in cervical lymph node metastasis of papillary thyroid carcinoma. Methods A total of 112 patients with thyroid papillary carcinoma underwent preoperative color Doppler ultrasound and computed tomography (CT) examination. The results of color Doppler ultrasonography, computed tomography and color Doppler ultrasonography combined with CT were evaluated based on the results of pathological examination. Results There were 92 cases (82.1%) of cervical lymph node metastasis and 20 cases (17.9%) without cervical lymph node metastasis after operation. There was no significant difference between the two groups in the predictive value of color Doppler ultrasound, CT and color Doppler ultrasonography (P> 0.05) Color Doppler ultrasound combined with CT negative predictive value and diagnostic accuracy was significantly higher than CT, the difference was statistically significant (P <0.05). Conclusion Preoperative color Doppler ultrasonography combined with CT in the diagnosis of cervical lymph node metastases of thyroid papillary carcinoma is more accurate than simple CT, which provides an important reference for the clinical choice of surgery.
