# Description
This model is a [MedRoBERTa.nl](https://huggingface.co/CLTL/MedRoBERTa.nl) model finetuned on Dutch echocardiogram reports sourced from Electronic Health Records. 
The publication associated with the span classification task can be found at https://arxiv.org/abs/2408.06930. 
The config file for training the model can be found at https://github.com/umcu/echolabeler.

# Minimum working example
```python
from transformer import pipeline
```
```python
le_pipe = pipeline(model="UMCU/Echocardiogram_aortic_stenosis_reduced")
document = "Lorem ipsum"
results = le_pipe(document)
```

| Component | Labels |

Here, for the reduced labels `Present` means that for *any one or multiple* of the pathologies we have a positive result.

| pe  | Pericardial Effusion |
| wma | Wall Motion Abnormality |
| lv_dil | Left Ventricle Dilation |
| rv_dil | Right Ventricle Dilation |
| lv_syst_func | Left Ventricle Systolic Dysfunction |
| rv_syst_func | Right Ventricle Systolic Dysfunction |
| lv_dias_func | Diastolic Dysfunction |
| aortic_valve_native_stenosis | Aortic Stenosis |
| mitral_valve_native_regurgitation | Mitral valve regurgitation |
| tricuspid_valve_native_regurgitation | Tricuspid regurgitation |
| aortic_valve_native_regurgitation | Aortic Regurgitation |
</details>

Note: `lv_dias_func` should have been `dias_func`..

# Intended use
The model is developed for *document* classification of Dutch clinical echocardiogram reports.
Since it is a domain-specific model trained on medical data, it is **only** meant to be used on medical NLP tasks for *Dutch echocardiogram reports*.

# Data
The model was trained on approximately 4,000 manually annotated echocardiogram reports from the University Medical Centre Utrecht.
The training data was anonymized before starting the training procedure.
