Recently, researchers have successfully applied a MSDE
(or FSD) prepared non-contrast-enhanced (NCE) MRA
technique to anatomies like distal lower extremities,
hand and foot. However the proposed method requires
excessive additional pre-scans to determine the optimal
imaging parameters, which is not suitable for widespread
use clinically, especially when it comes to imaging of
the three stations of lower extremities. This study
optimized and accelerated the iMSDE prepared NCE-MRA
technique in three aspects to facilitate easier and
faster scans in clinical practice.
