The long scan time in cine PCMRI is due to high temporal
and high spatial resolution. It can accelerate scan time
using keyhole technique, but also make blurred image in
phase encoding direction. Although the blurred image can
be modified and looks like a high resolution image, the
retrieved intensity value in phase image may be
different with original value. In this study,
simulations on the numerical phantom and reducing the
number of central k-space line from a real cine PCMRI
with high temporal and spatial resolution were used to
evaluate the phase cross-contamination by keyhole scan.
