This study aimed to explore the utility of two-dimensional susceptibility-weighted imaging (2D-SWI) for assessing the fetal osseous spine. Whole-spine MRI was performed on fetuses, which included 2D-SWI and T2-weighted true fast imaging with steady-state precession (T2-TrueFISP) sequences. The image quality of the 2D-SWI was superior to the T2-TrueFISP, allowing for improved diagnostic accuracy in the diagnosis of spinal abnormities. 2D-SWI was valuable in elucidating the structures of the fetal osseous spine allowing for better assessment of spinal deformity, especially in the cervical segment of the spine.
