Fetal MRI provides detailed fetal anatomy and is being
increasingly used to evaluate fetal development.
However, the image quality is degraded by the fetal
motion and maternal respiratory and involuntary
movements during long acquisition time. In this study,
we applied the interpolated compressed sensing method to
accelerate the acquisition and increase contrast to
noise ratio (CNR) for multi-slice two-dimensional MR
imaging. By combining with parallel imaging, the
acquisition time can be further reduced. In-vivo MR of a
pregnant woman has been used to investigate the
feasibility of this method, showing obviously increased
CNR compared with the conventional CS.
