| Challenge: | Existing methods for medical image analysis use predefined template databases or ignore hierarchical nature of medical report generation. |
| Approach: | They propose a hierarchical retrieval mechanism to extract both report and sentence-level templates for clinically accurate report generation. |
| Outcome: | The proposed model extracts both report and sentence-level templates for clinically accurate report generation. |

| Challenge: | Existing efforts to improve medical question answering performance follow two directions. |
| Approach: | They propose a framework that combines a generalist with a domain-specific specialist without any model fine-tuning or parameter updates. |
| Outcome: | The proposed framework boosts GPT-4o accuracy by 13.8%, deepseek-R1 by 16.8%, and improves a vanilla 7B model from 14.1% to 23.9%. |
