Synopsis

This study explored the feasibility and clinical value of susceptibility weighted imaging (SWI) in depicting fetal vertebral growth and related anomalies. The results showed that vertebral development in fetuses on SWI was remarkably linearly correlated with gestational ages. In addition, SWI demonstrated superior image quality and higher diagnostic accuracy compared to conventional Half-Fourier acquisition single-shot turbo spin-echo (HASTE) or true fast imaging with steady-state precession (TrueFISP) sequences. In conclusion, SWI is a reliable choice when imaging fetal vertebrae and vertebral anomalies.
