The T1-weighted, dual gradient-echo in-phase
/opposed-phase imaging sequence has become a routine
part of every hepatic MR imaging protocol. It is a
helpful tool to detect focal liver lesions. This
sequence is conventionally performed before contrast
injection. Gd-EOB-DTPA is a FDA approved liver-specific
gadolinium compound. When Gd-EOB-DTPA is used,
hepatic-phase imaging can be acquired ~20 minutes after
the injection. To streamline the overall protocol, it is
desirable to move the dual echo sequence from
pre-contrast to post-contrast. The aim of this study is
to compare dual-echo data pre and post contrast and
evaluate its effect in detecting focal liver lesions
