Dynamic contrast-enhanced (DCE)-MRI has emerged as an
important method for evaluating tumor blood flow and
treatment response to antivascular agents. However, it
is difficult to acquire good DCE-MRI of abdomen or
thorax due to the respiratory motion. To overcome the
respiratory motion artifact, we evaluated the
feasibility of free-breathing dynamic contrast-enhanced
MRI (DCE-MRI) of the abdomen and thorax at 3.0 T using
CAIPIRINHA-VIBE and radial VIBE with KWIC
reconstruction. Our results showed that they can
overcome respiratory motion while providing high spatial
and temporal resolution.
