On Gd-EOB-DTPA-enhanced MRI for detection of HCC, 10-min delayed hepatocyte phase imaging using a 30 flip angle had higher or similar lesion-to-liver CNR and detection sensitivity, compared to 20-min delayed hepatocyte phase imaging with 10 or 30 flip angle. This result indicates that 10-min delayed hepatocyte phase imaging with a 30 FA could replace 20-min delayed hepatocyte phase imaging with better or similar diagnostic performance for the detection of HCC and also allows 10 minutes of time-saving.
