| 摘 要： | 本文探讨了计算机断层扫描（CT）、磁共振成像（MRI）对良恶性甲状腺结节的鉴别价值。方法：选取2015年3月至2018年3月本院收治的甲状腺结节患者150例，依据病理结果分为恶性48例、良性102例，所有患者均给予CT、MRI检查，分析CT、MRI对良恶性甲状腺结节的鉴别价值。结果发现，MRI总病灶、形态不规则、边界不清/毛糙、信号/密度不均检出率明显高于CT，MRI钙化灶检出率明显低于CT，差异有统计学意义（P<0.05），CT、MRI淋巴结转移检出率比较，差异无统计学意义（P>0.05）；在鉴别良恶性甲状腺结节的敏感度、特异度、准确度中，CT为79.17%、74.51%、76.00%，MRI为83.33%、80.39%、81.33%，CT联合MRI为95.83%、96.08%、96.00%，CT联合MRI明显高于CT、MRI，差异有统计学意义（P<0.05）。说明CT、MRI可作为鉴别良恶性甲状腺结节的重要方法，CT对钙化灶有较高的分辨能力，MRI对软组织及小病灶有较高的分辨能力，CT联合MRI可有效提高其鉴别价值。

| Abstract: | To discuss the distinguishing value of computed tomography (CT) and magnetic resonance imaging (MRI) for benign and malignant thyroid nodules, 150 patients with thyroid nodules were selected from March 2015 to March 2018 in our hospital. According to the pathological results, they were divided into 48 cases malignant and 102 cases benign, all patients were examined by CT and MRI. The distinguishing value of CT and MRI for benign and malignant thyroid nodules was analyzed. The total focus, irregular shape, unclear boundary/roughness, signal/density uneven detection rate in the MRI were significantly higher than those in the CT, the calcification detection rate in the MRI was significantly lower than that in the CT, the difference was statistically significant (P<0.05). The comparison of the lymph node metastasis detection rate in the CT and MRI, the difference was not statistically significant (P>0.05). In the sensitivity, specificity, accuracy of the distinguishing value for benign and malignant thyroid nodules, the CT were 79.17%, 74.51%, 76%, the MRI were 83.33%, 80.39%, 81.33%, the CT combined MRI were 95.83%, 96.08%, 96.00%, the CT combined MRI were significantly higher than the CT or the MRI, the difference was statistically significant (P<0.05). Conclusions:CT and MRI can be used as the important method for differentiating benign and malignant thyroid nodules, CT has the high resolution to calcification, MRI has the high resolution to soft tissue and small lesions, CT combined with MRI can effectively improve their distinguishing value. |
