- 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.
