目的 探讨高频超声联合CT检查 在甲状腺乳头癌临床诊断中的应用价值。 方法 回顾性分析我院2016年1月-2017年 12月收治的150例甲状腺乳头癌患者临床 资料，根据影像学诊断措施的不同分为三 组，其中50例患者接受单纯高频超声检 查，纳入单纯超声组；另52例患者接受单 纯CT检查，纳入单纯CT组；其余48例患 者接受高频超声联合CT检查，纳入联合 组。结果 病理诊断结果显示，150例甲状 腺乳头癌患者中单侧单发63.33%，单侧 多发19.33%，多侧多发13.33%，多侧单 发4.00%。伴微小钙化56.00%，其中合并 甲状腺弥漫性病变31.58%，合并结节性 甲状腺肿22.11%，合并甲状腺滤泡性腺 瘤22.11%。CT组影像学特征：78.00%患者 甲状腺肿瘤边界模糊，496.00%回声不均 匀，100.00%钙化。58.00%患者诊断为甲 状腺腺瘤。68.00%向周边侵犯，60.00%为 蟹足状。图片可见颈部出现多个或单个圆 形、椭圆形实质性低回声结节。超声影像 学特征：96.15%患者甲状腺实质沙粒样钙 化，78.85%回声显示不均质，且回声紊 乱，无规则，未发现明显结节。高频超声 显示，88.46%患者病灶血流成像丰富， 19.23%患者血流紊乱。联合组影像学特 征：48.50%肿瘤边缘形态不规则，边界模 糊100.00%，回声不均匀83.33%，钙样化 100.00%。故联合诊检出率为100%。结论 联合诊断甲状腺乳头癌能显著提高检出 率，明确肿瘤形态及浸润程度，可促进治 疗。

Objective To investigate the application value of high frequency ultrasound combined with CT in clinical diagnosis of thyroid papillary carcinoma. Methods The clinical data of 150 patients with thyroid papillary carcinoma admitted to our hospital from January 2016 to December 2017 were retrospectively analyzed. Patients were divided into three groups, ultrasound group (frequency ultrasound), CT group (CT) and combined group (frequency ultrasound combined with CT) according to the image examination methods. Results The pathological diagnosis results showed that 63.33% were unilateral, 19.33% were unilateral, 13.33% were multisided, and 4.00% were multisided among 150 patients with thyroid papillary carcinoma. With 56.00% of microcalcifications, 31.58% of them were combined with thyroid diffuse lesions, 22.11% of grouped nodular goiters, and 22.11% of thyroid follicular adenomas. CT imagings featured that 78.00% of patients had ambiguous boundaries of thyroid tumors, 496.00% of echoes were uneven, and 100.00% had calcification. 58.00% of patients were diagnosed as thyroid adenomas. 68.00% violated the surrounding area, and 60.00% was crab-footed. The picture shows multiple or single round, oval, substantially hypoechoic nodules appearing on the neck. Ultrasonographic featured that 96.15% of patients had thyroid parenchymal calcification, 78.85% had not homogenous, disorder and irregular echoes with no obvious nodules. High-frequency ultrasonography showed that 88.46% of patients had rich blood flow imaging, and 19.23% had abnormal blood flow. The images of the combined group showed that the 487.50% had irregular tumor margins, 100.00% had blurred borders, 83.33% had uneven echoes, and 100.00% had calcifications. So the combined detection rate was 100%. Conclusion The combined diagnosis of thyroid papillary carcinoma can significantly increase the detection rate, which can clarify the tumor shape and the infiltration degree.
