A novel model based on apparent diffusion coefficient and signal intensity on MRI to quantify subtle internal difference between tumor-adjacent and -distant liver tissues in T3-staged resectable gallbladder carcinoma

Key Points

• To develop a model that quantifies differences between tumor-adjacent and distant liver tissues in T3-staged gallbladder carcinoma.
• Utilized MRI techniques to analyze apparent diffusion coefficient and signal intensity.
• Focused on the distinction between tumor-adjacent tissues (TAL) and tumor-distant tissues (TDL).
• The model effectively differentiates between TAL and TDL.
• Quantification of subtle differences was achieved in T3-staged gallbladder carcinoma.
