In this study, we evaluate the usage of Parallel Imaging
and Compressed Sensing to accelerate a recently proposed
four dimensional, non-breath-hold, multiphase
steady-state imaging technique (MUSIC), in hope to
decrease acquisition time and increase temporal
resolution. Based on initial experience on nine
pediatric patients with congenital heart disease,
accelerated MUSIC has similar image quality with half
acquisition time, compared with original MUSIC. Image
reconstruction is implemented in C/C++ that allows
clinically acceptable reconstruction time, make it
feasible for practical usage.
