# LLaVA-Med model for multimodal radiology report generation

This is a model based on LLaVA-Med 1.0, finetuned to generate medical reports, based on a chest X-ray and a prompt, 
in our case, the instruction was "write the finding section of a chest x-ray radiology report".

The dataset used for finetuning was the MIMIC-CXR  share for the challenge in Radiology Report Generation 
for the Association for Computational Linguistics 2024 at BioNLP Workshop 

We used the 148,374 findings of MIMIC-CXR for finetuning during 3 epochs. 

The model metrics on the 1,063 samples of the hidden test set of the ACL challenge are the following:

| Method      | BLEU-4 | Rouge-L | Bertscore | F1-CheXbert | F1-RadGraph | Avg   |
|-------------|--------|---------|-----------|-------------|-------------|-------|
| llavamed1.0 |  5.05  |  19.13  |   47.51   |    23.06    |    15.77    | 22.10 |


The metrics were calculated direcly by the challenge organizer, however you can reproduce them with the following 
example code:

```python
import json
import logging
from vilmedic.blocks.scorers.scores import compute_scores

refs = [
    "The lungs are clear. The cardiomediastinal silhouette is within normal limits. No acute osseous abnormalities.",
    "The lungs are clear.There is no pleural effusion or pneumothorax.The cardiomediastinal silhouette is normal."
]
hyps = [
    "The lungs are clear. There is no pleural effusion or pneumothorax. The cardiomediastinal silhouette is normal.",
    "The lungs are clear. The cardiomediastinal silhouette is within normal limits. No acute osseous abnormalities."
]
print("Computing metrics, this can take a while...")
print(json.dumps(compute_scores(["ROUGEL", "bertscore", "radgraph", "BLEU", "chexbert"],
                                refs=refs,
                                hyps=hyps,
                                split=None,
                                seed=None,
                                config=None,
                                epoch=None,
                                logger=logging.getLogger(__name__),
                                dump=False),
                 indent=4)
      )
```
