The radial volumetric imaging breath-hold examination
with k-space-weighted image contrast reconstruction
(r-VIBE-KWIC) allows powerful view sharing and provides
high temporal resolution sub-frame images as well as a
full-frame image. Dynamic contrast-enhanced MRI
(DCE-MRI) using r-VIBE-KWIC has the potential to provide
high spatial and temporal resolution images like a
dynamic CT during hepatic arteriography (dyn-CTHA)
without an invasive procedure or radiation exposure. We
compared hemodynamics of HCC in DCE-MRI using
r-VIBE-KWIC with that in dyn-CTHA, and revealed that
DCE-MRI using r-VIBE-KWIC had a diagnostic potential
comparable to dyn-CTHA in the hemodynamic evaluation of
HCC.
