目的分析超声、RMI、CT在诊断 原发性胆囊癌中的应用价值。方法 回顾 性分析经手术病理证实的50例原发性胆囊 癌患者影像学资料，所有患者均行超声检 查，行CT检查40例，行MRI检查25例，观 察分析各自影像学表现，同时与手术病理 检查结果对照，比较三者原发性胆囊癌诊 断正确率。结果 与手术病理结果比较， 超声、CT、MRI诊断相符率（正确率）分 别为64.0%、73.3%、88.0%，MRI诊断正确 率明显高于超声，差异有统计学意义（P ＜0.05）。结论 超声、MRI、CT在原发性 胆囊癌诊断中各有优缺点，其中MRI诊断 相符率最高，超声诊断相符率最低。

Objective To analyze the application value of ultrasound, MRI and CT in the diagnosis of primary gallbladder carcinoma. Methods The imaging data of 50 patients with primary gallbladder carcinoma confirmed by operation and pathology were retrospectively analyzed. All patients underwent ultrasound examination. 40 cases underwent CT examination and 25 cases underwent MRI examination. The imaging findings were observed and analyzed, respectively. Meanwhile, the findings were compared with the results of operation and pathological examination. The accuracy of the three kinds of examinations in the diagnosis of primary gallbladder carcinoma was compared. Results Compared with operation and pathological results, the diagnostic accordant rates (accuracy) of ultrasound, CT and MRI were 64.0%, 73.3% and 88.0%. The diagnostic accuracy of MRI was significantly higher than that of ultrasound, and the difference was statistically significant (P<0.05). Conclusion Ultrasound, MRI and CT in the diagnosis of primary gallbladder carcinoma have their own advantages and disadvantages, and the diagnostic accordant rates of MRI was the highest while of ultrasound was the lowest.
