A steady-state free precession (SSFP) sequence is used in many MR enterography (MRE) protocols for acquiring cine images to assess bowel motility, inflammation, and strictures. However, SSFP suffers from susceptibility and banding artifacts that become more significant at high field strengths. In this IRB approved retrospective study, we compared a cine SSFP sequence to a cine T2-weighted single-shot fast spin echo (SSFSE) sequence in 41 patients. We found SSFSE demonstrated significantly superior subjective assessments of image quality, improved diagnostic performance compared to cine SSFP, and successfully mitigated SSFP artifacts that can otherwise limit the exam.
