Magnetic resonance (MR) imaging appears to be increasing used for the diagnosis of abnormalities in fetuses because of the absence of ionizing radiation and superior contrast of soft tissues. However, the T1-weighted 3D MR imaging for fetus remains very challenging due to the respiratory motion of the mother and the movement of the fetus. In this study, we evaluated the feasibility of a free-breathing 3D T1-weighted gradient-echo imaging with radial data sampling for fetus imaging, and compared with a standard breath-hold imaging with Cartesian k-space acquisition
