This study explored the scanning strategy of fetal spine imaging using Magnetic Resonance Imaging (MRI) on 315 volunteer pregnant subjects. Whole-spine MRI was performed on fetuses using Susceptibility-Weighted Imaging (SWI) and True Fast Imaging with Steady-state Precession (TrueFISP) sequences. Images from both methods were acquired, and the diagnostic efficacy was compared. The SWI showed superior performance in visualizing osseous spinal anomalies, while TrueFISP better presented spinal canal contents lesions. Additionally, the MRI was preferred for the diagnosis of fetal spinal diseases to US. These mixed results suggest that a combination of both techniques is appropriate for fetal spine imaging.
