Traditional breath-hold, fat-suppressed T1-weighted sequences (T1W images) may be degraded by motion artifacts arising from both the mother and fetus. Images obtained with the radial VIBE sequence had a higher overall image quality score than Cartesian sampled 3D VIBE T1W images and less motion artifact in various fetal regions. Fetal lesions presented in radial VIBE images had good lesion conspicuity and edge sharpness.
