Comparison of preoperative and intraoperative MRI scores for optic chiasm visualization. (A) Box plot comparing the median scores of preoperative contrast-enhanced bSSFP (3.0 (IQR: 2.75–3.0)) and preoperative T2WI (2.0 (IQR: 1.0–2.0)). The median score for contrast-enhanced bSSFP was significantly higher than that for T2WI (p = 0.0002), indicating better visualization with contrast-enhanced bSSFP. (B) Box plot comparing the median scores of intraoperative contrast-enhanced bSSFP (3.0 (IQR: 2.0–3.0)) and intraoperative T2WI (2.0 (IQR: 1.0–2.0)). The median score for contrast-enhanced bSSFP was significantly higher than that for T2WI (p = 0.0002), indicating enhanced visualization with contrast-enhanced bSSFP.
