摘要:
 目的：探讨胆囊癌及其病灶局部侵犯的MRI影像学特征及在胆囊癌临床诊断中的应用价值。方法：选择阜新矿业（集团）有限责任公司总医院2016年6月~2018年6月收治的70例诊胆囊癌患者进行前瞻性研究，所有患者进行MRI与螺旋CT检查。以手术病理或活检病理结果为基准，计算两种检查方法诊断胆囊癌的敏感性与特异性及局部组织器官侵犯（包括胆管受侵、肝脏直接受侵、肝门淋巴结受侵、胰腺受浸润）的检出率并进行比较。总结MRI诊断胆囊癌的影像学表现特征。结果：70例患者中经手术病理或活检证实胆囊癌60例、胆囊良性肿物10例。MRI诊断胆囊癌的敏感性为96.67%（58/60），高于螺旋CT的85.00%（51/60），差异有统计学意义（P<0.05）。MRI诊断胆囊癌的特异性为80.00%（8/10），螺旋CT为60.00%（6/10），差异无统计学意义（P>0.05）。MRI对胆管受侵与肝脏直接受侵的检出率分别为100%（30/30）与94.12%（32/34），高于螺旋CT的80.00%（24/30）与73.53%（25/34），差异有统计学意义（P<0.05）。结论：MRI诊断胆囊癌具有较高的敏感性与特异性，且有利于准确评估肿瘤局部浸润范围，可提高对病灶局部侵犯的检出率，较螺旋CT有更大的临床价值，值得推广应用。
Abstract:
 Abstract: Objective To explore the magnetic resonance imaging (MRI) features of gallbladder carcinoma and local invasion and its application in the diagnosis of gallbladder carcinoma. Methods A prospective study on 70 patients with suspected gallbladder carcinoma admitted to Fuxin Mining Group General Hospital from June 2016 to June 2018 was conducted. All patients underwent MRI and spiral CT examinations. Based on the pathological results obtained by surgery or biopsy, two inspection methods were used to diagnose the sensitivity and specificity of gallbladder carcinoma. The detection rates of local invasions, including bile duct invasion, direct infiltration into the liver, hilar lymph node invasion and infiltration into the pancreas, were compared. Finally, the MRI features for the diagnosis of gallbladder carcinoma were summarized. Results The results of surgery or biopsy showed that there are 60 cases of gallbladder carcinoma and 10 cases of benign gallbladder tumors. The sensitivity of MRI in the diagnosis of gallbladder carcinoma was 96.67% (58/60), which was higher than 85.00% (51/60) of spiral CT, with statistical differences (P<0.05). However, the specificity of MRI in the diagnosis of gallbladder carcinoma was similar to that of spiral CT, without statistical differences ［80.00% (8/10) vs 60.00% (6/10), P>0.05］. The detection rates of MRI on bile duct invasion and direct invasion of the liver were 100% (30/30) and 94.12% (32/34), respectively, higher than 80.00% (24/30) and 73.53% (25/34) of spiral CT, with statistical differences (P<0.05). Conclusion MRI for the diagnosis of gallbladder carcinoma has high sensitivity and specificity, which is conducive to accurately assess the extent of local invasion of the tumor and improve the detection rate of local invasion of the tumor. MRI has greater clinical value than spiral CT and is worthy of popularization and application.
