Magnetic resonance image (MRI) has been increasingly used to evaluate fetal malformations. Currently, the commonly used fetal spine scanning sequences include conventional 2D Single-Shot TSE (2D SSH TSE) and 2D balanced fast field echo sequence (2D BTFE), However, 2D MR sequences have disadvantages such as unclear display of tiny structures especially the fetal cervical vertebra, furthermore the image quality is strongly affected by fetal postures. In this study we compared 3D T2-star-weighted FFE sequence with conventional 2D SSH TSE sequence and 2D BTFE sequence. The 3D T2-star FFE sequence has high prenatal diagnosis value for fetal spine malformation, and can be used as an important supplementary sequence for fetal spine diagnosis in clinical practice.
