Comparison of reduced FOV diffusion-weighted imaging of rectal cancer at 5.0T ultra-high field versus 3.0T MRI: image quality and histopathological T staging

Key Points

• This research aims to compare the effectiveness of reduced FOV diffusion-weighted imaging at 5.0T and 3.0T MRI for rectal cancer staging.
• Compared image quality and ADC values of rectal cancer using 5.0T and 3.0T MRIs.
• Assessed histopathological T staging based on imaging results.
• Utilized diffusion-weighted imaging to evaluate tumor visualization.
• 5.0T diffusion-weighted imaging showed enhanced image quality compared to 3.0T MRI.
• Mean tumor ADC values were significantly different between the two MRI settings.
• Improved visualization may aid in accurate histopathological T staging.
