# Radiology Report Summarization

This model summarizes radiology findings into accurate, informative impressions to improve radiologist-clinician communication.

## Model Highlights

- **Model name:** Radiology_Bart
- **Author:** [Muhammad Bilal](linkedin.com/in/muhammad-bilal-6155b41aa)
- **Model type:** Sequence-to-sequence model
- **Library:** PyTorch, Transformers
- **Language:** English

### Parent Model 
- **Repository:** [GanjinZero/biobart-v2-base](https://huggingface.co/GanjinZero/biobart-v2-base)
- **Paper:** [BioBART: Pretraining and Evaluation of A Biomedical Generative Language Model](https://arxiv.org/pdf/2204.03905.pdf)
 
This model is a version of pretrained BioBart-v2-base model further finetuned on 70,000 radiology reports to generate radiology impressions. It produces concise, coherent summaries while preserving key findings.

## Model Architecture

Radiology_Bart is built on the BioBart architecture, a sequence-to-sequence model which is pre-trained on biomedical-text-data[PubMed](https://pubmed.ncbi.nlm.nih.gov/). The encoder-decoder structure allows it to compress radiology findings into impression statements.

Key components:

- Encoder: Maps input text to contextualized vector representations
- Decoder: Generates output text token-by-token
- Attention: Aligns relevant encoder and decoder hidden states  

## Data

The model was trained on 70,000 deidentified radiology reports split into training (52,000), validation (8,000), and test (10,000) sets. The data covers diverse anatomical regions and imaging modalities (X-ray, CT, MRI).

## Training

- Optimization: AdamW 
- Batch size: 16
- Learning rate: 5.6e-5
- Epochs: 4

The model was trained to maximize the similarity between generated and reference impressions using ROUGE metrics.

## Performance

  **Evaluation Metrics** 
  
| ROUGE-1 score | ROUGE-2 score | ROUGE-L score | ROUGELSUM score |
|---------------|---------------|---------------|-----------------|
|   44.857      |    29.015     |     42.032    |    42.038       |

Demonstrating high overlap with human references.

## Usage

```python
from transformers import AutoTokenizer, AutoModelForSeq2SeqLM, Pipeline

# Sample findings 
findings = "There is a small lung nodule in the right upper lobe measuring 6 mm. The heart size is normal. No pleural effusion or pneumothorax."

# Load model & tokenizer
summarizer = pipeline("summarization", model="Mbilal755/Radiology_Bart")
tokenizer = AutoTokenizer.from_pretrained("Mbilal755/Radiology_Bart")

# Tokenize findings
inputs = tokenizer(findings, return_tensors="pt")

# Generate summary 
summary = summarizer(findings)[0]['summary_text']

# Print outputs
print(f"Findings: {findings}")
print(f"Summary: {summary}")
```

## Limitations

This model is designed solely for radiology report summarization. It should not be used for clinical decision-making or other NLP tasks.
