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.
