To optimize Gd-EOB-DTPA-enhanced MR imaging protocol in the diagnosis of hepatic tumors. We analyzed the timing of the dynamic phase, hepatocyte phase and diffusion weighted imaging (DWI). In normal bilirubin level, imaging at 10 minutes was comparable to 20 minutes. In abnormal bilirubin level, no significant difference of CNR was found between 15 minutes and 20 minutes. Gd-EOB-DTPA did not affect the quality of DWI. @ Optimized protocol offered the shortening of Primovist-enhanced MR examination time without the impairment of diagnostic performance.
