ABSTRACT
Objective:
To study magnetic resonance imaging (MRI) in differential diagnosis between benign and malignant gallbladder diseases.Methods:
A retrospective study was conducted on 115 patients with gallbladder diseases managed at Nankai Hospital from August 2017 to August 2019. There were 50 males and 65 females, with the age of (57±12) years. Patients who underwent MRI and surgery were studied and the surgical histopathological examination was used as the gold standard. The MRI imaging findings in differentiating between benign and malignant gallbladder diseases were evaluated.Results:
Of 115 patients, histopathological examination showed 70 patients had benign lesions, which included 24 gallbladder polyps, 19 adenomyomatosis of gallbladder, 18 gallstones or bile duct stones, and 9 gallbladder adenomas. Of the 45 patients with malignancies, there were 37 gallbladder adenocarcinomas and 8 squamous cell carcinomas of gallbladder. MRI examination on these 115 patients showed 64 benign and 42 malignant lesions. The overall compliance rate was 92.2% (106/115). The sensitivity, specificity, positive predictive and negative predictive value of MRI in the differential diagnosis between benign and malignant gallbladder diseases were 93.3% (42/45), 91.4% (64/70), 87.5% (42/48) and 95.5% (64/67), respectively. The Kappa value of MRI compared with the gold standard was 0.838, showing good consistency.Conclusion:
MRI was useful, in the differential diagnosis between benign and malignant gallbladder diseases.
