Assessment of multi-parameter dual-energy CT in predicting muscle invasion in bladder cancer: comparison with VI-RADS

Key Points

• This research aims to evaluate the effectiveness of dual-energy CT (DECT) in predicting muscle invasion in bladder cancer compared to the VI-RADS scoring system.
• Utilized a multi-parameter dual-energy CT (DECT) model for assessment
• Compared diagnostic outcomes to the established VI-RADS system
• Evaluated preoperative differentiation of muscle invasion in bladder cancer cases
• DECT showed a diagnostic accuracy similar to that of VI-RADS
• DECT improved diagnostic confidence specifically in VI-RADS 3-4 lesions
