We compared the breathing motion artifact and signal
stability of conventional VIBE, Radial-VIBE with KWIC
view-sharing, and CAIPIRINHA-VIBE with moving phantom to
simulate breathing motion. Among the three sequences,
the CAIPIRINHA-VIBE showed the best image quality, in
that the phantom images maintained its shape and just
moved its position anteriorly/posteriorly. Thus, the
motion correction could align the CAIPIRINHA-VIBE images
very well. In terms of signal stability, the
CAIPIRINHA-VIBE with motion correction was the best. In
conclusion, CAIPIRINHA-VIBE is quite feasible for
free-breathing DCE-MRI with high image quality and high
temporal resolution.
