## Evaluation
|
| 171 |
-
|
| 172 |
-
The model is evaluated using standard medical NLG metrics with additional temporal reasoning evaluation:
|
| 173 |
-
|
| 174 |
-
- **RadGraph F1**: Measures clinical entity and relation extraction accuracy
|
| 175 |
-
- **BLEU**: N-gram overlap with reference reports
|
| 176 |
-
- **ROUGE** (ROUGE-1, ROUGE-2, ROUGE-L): Recall-oriented metrics
|
| 177 |
-
- **BERTScore**: Semantic similarity using contextual embeddings
|
| 178 |
-
- **CheXbert F1**: Clinical accuracy for pathology classification
|
| 179 |
-
- **Temporal consistency**: Evaluation of comparison statements and longitudinal reasoning
|
| 180 |
-
|
| 181 |

## Limitations
|
| 184 |
-
|
| 185 |
-
- Trained exclusively on chest X-ray images (not applicable to other imaging modalities)
|
| 186 |
-
- Performance may vary on images from different institutions or imaging protocols
|
| 187 |
-
- May not capture all rare pathologies or edge cases
|
| 188 |
-
- Requires expert radiologist review before clinical use
|
| 189 |
-
- Temporal reasoning accuracy depends on quality of prior study information
|
| 190 |
-
- Should not be used as the sole diagnostic tool
|
| 191 |
-
|
| 192 |
-
## Ethical Considerations
|
| 193 |
-
|
| 194 |
-
- **Medical AI Responsibility**: This model generates medical text and must be used responsibly
|
| 195 |
-
- **Human Oversight Required**: All outputs should be reviewed by qualified radiologists
|
| 196 |
-
- **Data Privacy**: Ensure compliance with HIPAA, GDPR, and local healthcare regulations
|
| 197 |
-
- **Bias and Fairness**: Model trained on specific datasets may have biases; validate on diverse populations
|
| 198 |
-
- **Clinical Validation**: Requires thorough validation before any clinical deployment
|
| 199 |
-
- **Longitudinal Data Handling**: Ensure proper patient consent and data governance for temporal data
