摘　　要：目的探讨甲状腺结节的CT及MRI临床诊断价值。方法选择2015年2月—2016年12月在本院行手术治疗的甲状腺结节50例患者作为研究对象。50例患者均经病理证实为甲状腺结节,术前行MRI、CT扫描检查,术后统计患者病理学报告分别与CT及MRI诊断结果进行比较,统计CT/MRI与病理诊断结果符合率。结果良性病例CT与病理诊断结果符合率(94.74%)略高于MRI符合率(86.84%),差异不具有统计学意义P>0.05。恶性病例CT与病理诊断结果符合率(91.67%)高于MRI符合率(75.00%),差异具有统计学意义(P<0.05)。CT与病理诊断结果总符合率(94.00%)高于MRI总符合率(84.00%),差异具有统计学意义(P<0.05)。结论 CT对于甲状腺结节的鉴别诊断准确性优于MRI,临床诊断价值更高,应作为首选影像学检查手段。Objective To investigate the clinical value of CT and MRI in the diagnosis of thyroid nodules. Methods 50 patients with thyroid nodules surgically treated in our hospital from February 2015 to December 2016 were selected as the subjects of this study. 50 patients were pathologically confirmed thyroid nodules and preoperative MRI CT scan, postoperative pathological reports and statistics were compared with the CT and MRI diagnosis results, diagnosis coincidence rateof CT/MR/with pathological diagnosis counted, Results The coincidence rate of CT scan with pathological diagnosis in benign cases （94.74%） was slightly higher than that of MRI（86.84%）, without statistically significant difference, P〉0.05. The coincidence rate of CT scan with pathological diagnosis in malignant cases （91.67%） was significantly higher than that of MRI（75.00%）, with statistically significant difference （P〈0.05）. The total coincidence rate of CT with pathological diagnosis （94.00%） was significantly higher than that of MRI （84.00%） with statistically significant difference （P〈0.05）. Conclusion The accuracy of differential diagnosis of CT is better than MRI, clinical diagnostic value superior, which should be given priority in clinical diagnosis.
