Researchers have developed MMA-Former, a novel 3D architecture designed for predicting perineural invasion (PNI) in cholangiocarcinoma from MRI scans. This model utilizes a Coarse-Fine Transformer structure for multi-scale feature extraction and introduces a Window-Specific Mixture-of-Head attention mechanism. This mechanism allows for adaptive feature extraction by routing 3D windows to specialized attention heads, enhancing specialization and reducing redundancy. In evaluations on 168 MRI scans, MMA-Former achieved an AUC of 0.752, surpassing existing CNN and Transformer baselines. AI
