摘　　要：目的 分析3.0T MRI在鉴别黄色肉芽肿性胆囊炎(XGC)和厚壁型胆囊癌(GBC)中的价值.方法 回顾性分析经病理证实的XGC和厚壁型GBC患者的临床资料和MRI特征.结果 共128例患者纳入本研究,其中,XGC 53例,厚壁型GBC 75例.XGC和厚壁型GBC的壁内结节分别为44例和3例.XGC和厚壁型GBC的平均表观扩散系数(ADC)值分别为(1.557±0.195)×10^(-3) mm^(2)/s、(0.971±0.153)×10^(-3) mm^(2)/s,差异均有统计学意义(t=-19.03,P<0.001).患者性别、年龄、胆管扩张、强化方式、CA199等其余特征差异无统计学意义(P>0.05).结论 高场MRI能够清晰显示胆囊病变的具体情况.XGC的平均ADC值大于厚壁型GBC,在定性、定量鉴别XGC和厚壁型GBC有重要意义.Objective To analyze the value of 3.0T MRI in the differential diagnosis of xanthogranulomatous cholecystitis(XGC)and thick walled gallbladder carcinoma(GBC).Methods The clinical and MRI data of XGC and thick-walled GBC patients confirmed by pathology were analyzed retrospectively.Results A total of 128 patients were ineluded in this study,including 53 patients with XGC and 75 patients with thick-walled GBC.The intramural nodules of XGC and thick-walled GBC were 44 and 3,respectively.The mean apparent diffusion cofficient(ADC)values of XGC and thick walled GBC were(1.557±0.195)×10^(-3) mm^(2)/sand(0.971±0.153)×10^(-3) mm^(2)/s,respectively with statistical difference(t=-19.03,P<0.001).Gender,age,bile duct dilatation,enhancement mode,CA199 and other characteristics of the patients showed no significant differences(P>0.05).Conclusion High field MRI can clearly shows conditions of gallbladder lesions.The average ADC value of XGC is greater than that of thick:walled GBC,which is of great significance in the qualitative and quantitative identification of XGC and thick-walled GBC.
