目的 探讨甲状腺微小癌采用 MRI、CT、B超三种检测方式对其诊断 效果的对比分析。方法 回顾分析我院 在2013年9月至2015年7月进行诊治的 资料齐全的180例甲状腺微小癌患者， 所有患者均经过MRI、CT、B超三种检 测方式对其诊断，诊断结果与病理学 诊断结果进行对比，分别统计三种检 测方式的甲状腺微小癌阳性率。 结 果 本次研究中，甲状腺微小癌MRI的 阳性率为32.22%(58/180)、CT的阳性 率为33.89%(61/180)、B超的阳性率为 74.44%(134/180)，MRI与CT检测的阳性 率之间相比，差异无显著性，无统计 学意义(χ2 =0.11，P＞0.05)，MRI、CT 与B超检测的阳性率之间相比，差异有 显著性，有统计学意义(χ2 =64.46，P ＜0.01；χ2 =59.63，P＜0.01)。结论 甲 状腺微小癌MRI、CT、B超三种检测方法 中，B超检测的阳性率最高，对临床诊断 具有很强的指导意义，值得临床上进行 推广。

Objective To investigate the thyroid cancer using small MRI, CT, B ultrasonic three detection methods of comparative analysis of the effect of its diagnosis. Methods A retrospective analysis of our hospital in September 2013 to July 2015 for treatment of the information is complete 180 cases of thyroid cancer in patients with small, all patients were over three detection through MRI, CT, B patterns on their diagnosis, diagnosis and disease Neo diagnostic results were compared, respectively, the positive rate of thyroid microcarcinoma statistics three detection modes. Results The results of this study, the tiny thyroid cancer MRI positive rate of 32.22% (58/180), CT positive rate of 33.89% (61/180), B super-positive rate of 74.44% (134/180), MRI between positive rate compared with CT, the difference was not statistically significant, was not statistically significant (χ2 =0.11, P>0.05), the difference was significant between, MRI, CT and B-positive rate of detection, there was statistically significant (χ2 =64.46, P<0.01, χ2 =59.63, P<0.01). Conclusion Thyroid microcarcinoma of MRI, CT, B super three detection methods, the positive rate of B-test of the highest, has a strong guiding significance for clinical diagnosis, it is worth promotion clinically.
