彩超联合CT对甲状腺乳头状癌颈部微小转移淋巴的应用

目的探讨彩色多普勒超声与CT联合诊断甲状腺乳头状癌颈部微小转移淋巴中的临床价值。方法选取2016年1月至2017年8月我院收治的甲状腺乳头状癌患者68例,均进行CT及超声诊断,以病理检查结果为金标准来评价超声、CT及超声联合CT的检查率。结果超声对甲状腺乳头状癌恶性率为72.05%,CT对甲状腺乳头状癌的恶性率为83.82%,CT检出恶性率显著优于超声(P<0.05)。超声联合CT对甲状腺乳头状癌的恶性率为92.64%,显著优于单一CT与超声检查(P<0.05);术后病理诊断颈淋巴结转移61例(89.70%),无颈淋巴结转移7(10.29%);CT、超声、超声联合CT阳性预测值比较,差异有统计学意义(P<0.05);CT、超声联合CT准确率显著优于超声(P<0.05)。结论甲状腺乳头状癌颈部微小转移淋巴经CT与超声检出率比较,CT诊断效果显著较佳,通过超声联合诊断CT可显著增强甲状腺乳头状癌颈微小淋巴转移的检出率。

Application of Color Doppler Ultrasound Combined with CT in Small Metastatic Lymphatic Tissue of Papillary Thyroid Carcinoma

Objective To investigate the value of color Doppler ultrasound combined with CT in the diagnosis of cervical lymph node metastasis in papillary thyroid carcinoma. Methods 68 cases of papillary thyroid carcinoma treated in our hospital from January 2016 to August 2017 were selected. All patients received the color Doppler ultrasound and CT examinations, and the results were compared with those of the pathological examination results so as to determine the diagnosis rate of the two methods. Results The malignancy detection rate of CT was significantly higher than that of ultrasound(72.05% vs 83.82%, P<0.05). The malignancy detection rate of combined detection(92.64%) was higher than that of the single detection(P<0.05). Postoperative pathological diagnosis showed 61 cases(89.70%) with cervical lymph node metastasis and 7 cases without cervical lymph node metastasis(10.29%). Positive predictive values of CT, ultrasound and ultrasound combined with CT were significantly different(P<0.05). The diagnosis accuracy rate of combined detection was higher than that of the single detection(P<0.05). Conclusion Compared with the color Doppler ultrasound, the diagnosis rate of papillary thyroid carcinoma by CT is better, while the detection rate of cervical lymph node metastasis by combined method is higher than that of the single detection.
