Abstract: With the increasing richness of medical images and clinical data, abundant data support is provided for multimodal chest disease diagnosis methods. However, traditional multimodal fusion methods are often relatively simple, leading to insufficient exploitation of crossmodal complementary advantages. At the same time, existing multimodal chest disease diagnosis methods usually focus on two modalities, and their scalability is poor when extended to three or more modalities. Moreover, in practical clinical scenarios, missing modality problems often arise due to equipment limitations or incomplete data acquisition. To address these issues, this paper proposes a novel multimodal chest disease classification model, MDFormer. This model designs a crossmodal attention fusion mechanism, MFAttention, and combines it with the Transformer architecture to construct a multimodal fusion module, MFTrans, which effectively integrates medical imaging, clinical text, and vital signs data. When extended to multiple modalities, MFTrans significantly reduces model parameters. At the same time, this paper also proposes a two-stage masked enhancement classification and contrastive learning training framework, MECCL, which significantly improves the model’s robustness and transferability. Experimental results show that MDFormer achieves a classification precision of 0.8 on the MIMIC dataset, and when 50% of the modality data are missing, the AUC can reach 85% of that of the complete data, outperforming models that did not use two-stage training.
