Researchers have developed a new framework called CA-GCL to improve the understanding of 3D medical images. This method addresses the issue of text embeddings becoming too similar, making it difficult to distinguish between different anatomical structures. CA-GCL uses a global contrastive objective to separate these embeddings and a clinical-aware text augmentation strategy to enhance robustness against incomplete descriptions. Evaluations on CT-RATE and Rad-ChestCT datasets show that CA-GCL performs comparably to existing methods in zero-shot abnormality detection while being significantly more stable when faced with variations in prompts.
