Feasibility of 10-minute delayed hepatocyte phase imaging with 30 flip angle in Gd-EOB-DTPA-enhanced MRI for detection of liver metastases, compared to 20-minute delayed hepatocyte phase imaging with standard 10 flip angle.

On Gd-EOB-DTPA-enhanced MRI for detection of liver metastases, 10-min delayed hepatocyte phase imaging (HPI) using a 30 flip angle (FA) had higher lesion-to-liver CNR with no difference in lesion detection sensitivity compared to 20-min delayed HPI with a standard 10 FA. This result indicates that 10-min delayed HPI with a 30 FA could replace 20-min delayed HPI with better diagnostic performance for the detection of liver metastases and also allows 10 minutes of time-saving.
