目的分析胆囊结核患者 的 电 子 计 算 机 断 层 扫 描 ( Computed Tomography，CT)、磁共振成像(Magnetic Resonance Imaging，MRI)表现特点。 方法 选取我院300经临床病理检查证 实为胆囊结核患者纳入研究，均行CT 与MRI检查，对其临床资料进行回顾 性分析，总结CT、MRI表现特点。结 果 CT检查敏感度95.86%(278/290)， 特异度80.00%(8/10)，准确性 95.33%(286/300)，Kappa值=0.51； MRI检查敏感度94.83%(275/290)， 特异度70.00%(7/10)，准确性 94.00%(282/300)，Kappa值=0.41； MRI+CT检查敏感度97.93%(284/290)， 特异度80.00%(8/10)，准确性 97.33%(292/300)，Kappa值=0.65；CT表 现特点：胆囊壁增厚，并且囊内密度均 匀，和邻近肝脏界清晰；经过增强扫描发 现胆囊壁轻度强化；胆囊壁增厚，但是囊 内密度不均匀，和邻近肝脏界模糊；经过 增强扫描发现胆囊壁呈现不均匀强化，并 且有分隔状强化影。MRI表现特点：胆囊 区存在卵圆形异常信号，结核中央表现出 短T1以及长T2信号，病灶周围环绕带状短 T2与短T1信号，并且外层呈现半环状短T1 以及长T2信号。结论 胆囊结核在CT与MRI 检查结果中具有特征性表现，CT、MRI诊 断方式具有较高准确性，结合患者临床资 料，可为其诊治、预后评估提供重要指 导。

Objective To analyze the computed tomography (CT) and magnetic resonance imaging (MRI) manifestations of gallbladder tuberculosis. Methods 300 patients with gallbladder tuberculosis confirmed by clinical pathology were enrolled in the study. All patients were examined by CT and MRI, and their clinical data were retrospectively analyzed. CT and MRI manifestations were summarized. Results The sensitivity, specificity, accuracy and Kappa value of CT were 95.86% (278/290), 80.00% (8/10), 95.33% (286/300) and 0.51, respectively, while those of MRI were 94.83% (275/290), 70% (7/10), 94.00% (282/300) and 0.41, respectively. The sensitivity, specificity, accuracy and Kappa value of MRI+CT were 97.93% (284/290), 80.00% (8/10), 97.33% (292/300) and 0.65, respectively. The CT manifestations included thickening of the gallbladder wall, uniform density in the gallbladder, and clear boundary with the adjacent liver. Contrastenhanced scanning showed slight enhancement of the gallbladder wall, thickening of the gallbladder wall, uneven density in the gallbladder, unclear boundary with the adjacent liver, inhomogeneous enhancement of the gallbladder wall and separated enhancement shadow. MRI manifestations included oval abnormal signals in the gallbladder area, short T1 and long T2 signals in the center of the tuberculosis, lesions surrounded by short T2 and short T1 signals, and the outer layer showing semi-circular short T1 and long T2 signals. Conclusion CT and MRI manifestations of gallbladder tuberculosis are typical. The diagnostic accuracy rates of CT and MRI are high. They can provide important guidance for diagnosis and treatment and evaluation of the prognosis, combined with the clinical data.
