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
• Model type: Sequence-to-sequence model
• Library: PyTorch, Transformers
• Language: English

Parent Model

• Repository: GanjinZero/biobart-v2-base
• Paper: BioBART: Pretraining and Evaluation of A Biomedical Generative Language Model

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-dataPubMed. 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

Demonstrating high overlap with human references.

Usage

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.
