摘要 目的评价CT及MRI在中晚期胆囊癌周围脏器侵袭和转移中的诊断价值。方法回顾性分析我院2003年3月至2010年6月期间收治的经手术病理证实的中晚期胆囊癌患者45例,所有患者术前均同时行CT和MRI检查。结果①在诊断胆囊癌方面,CT诊断符合率为93.33%(42/45),MRI诊断符合率为88.89%(40/45),二者比较差异无统计学意义(χ2=0.287 2,P>0.05)。②在诊断胆囊癌转移的敏感度方面,肝脏直接浸润和转移诊断方面CT为72.00%(18/25),MRI为92.00%(23/25);胆管受侵诊断方面CT为83.33%(5/6),MRI为100%(6/6);胰腺转移诊断方面CT为100%(3/3),MRI为100%(3/3);淋巴结转移诊断方面CT为70.00%(7/10),MRI为90.00%(9/10);腹膜、网膜转移诊断方面CT为33.33%(1/3),MRI为33.33%(1/3)。诊断胆囊癌转移的总诊断符合率CT为72.34%(34/47),MRI为89.36%(42/47),MRI明显高于CT(χ2=4.083 3,P<0.05)。结论 MRI在诊断胆囊癌方面与CT相当,但在诊断肿瘤侵犯邻近器官及转移方面MRI略优于CT。
