Researchers have developed a novel method using Partial Information Decomposition (PID) to optimize the selection of multi-contrast 3D MRI sequences for training deep neural networks in brain tumor segmentation. This framework ranks input pairs based on their redundant, unique, and synergistic information, effectively identifying the most informative sequences. When applied to T1n, T1c, T2w, and T2-FLAIR MRI, the PID framework selected the T1c+T2-FLAIR pair, which, when used to train lightweight 3D U-Nets, achieved a mean Dice score of 0.676, closely rivaling the performance of using all four input sequences. Independent Shapley analysis further validated T2-FLAIR and T1c as the most influential inputs, demonstrating the practical utility of PID for reducing computational demands in medical imaging AI. AI
