A modified Time-resolved angiography With Stochastic
Trajectories (TWIST) sequence with flexible view sharing
and dual-echo DIXON was evaluated in clinical breast DCE-MRI
for its capability of measuring initial uptake phase
with fast acquisitions in addition to providing high
resolution peak- and post-contrast images. A good
correlation between the results based on the maximum
slope of the signal enhancement in the initial phase and
that based on the standard protocol was found,
indicating a potential of shortening the breast MRI scan
time and in turn a lowering of the breast MRI cost with
this new technique.
