This study aimed to investigate the feasibility of Gd-EOB-DTPA enhanced MRI in differentiating benign from malignant biliary obstruction at hepatobiliary phase (HBP) images. The liver enhancement ratio (LER) and the functional liver imaging (FLIS) score of benign and malignant biliary obstruction were significantly different. With these findings, Gd-EOB-DTPA enhanced MRI at HBP may be considered with an added clinical value in differentiating benign from malignant biliary obstruction.
