    The liver is normal in size and with normal parenchymal echogenicity with no
    sign of space-occupying lesion or bile ducts dilatation. GB is well
    distended with no stone or wall thickening. The spleen is normal in size and
    parenchymal echogenicity with no sign of space-occupying lesion. visualized
    parts of the pancreas and para-aortic area are unremarkable. Both kidneys
    are normal in size with normal cortical parenchymal echogenicity with no
    sign of the stone, stasis, or perinephric collection. ureters are not
    dilated. The urinary bladder is empty so evaluation of pelvic organs is not
    possible. no free fluid is seen in the abdominopelvic cavity.

## Introduction

This repository is code release for **Application of Deep Learning in Generating Structured Radiology Reports: A Transformer-Based Technique**

Since radiology reports needed for clinical practice and research are written and stored in free-text narrations, extraction of relative information for further analysis is difficult. In these circumstances, natural language processing (NLP) techniques can facilitate automatic information extraction and transformation of free-text formats to structured data. In recent years, deep learning (DL)-based models have been adapted for NLP experiments with promising results. Despite the significant potential of DL models based on artificial neural networks (ANN) and convolutional neural networks (CNN), the models face some limitations to implement in clinical practice. Transformers, another new DL architecture, have been increasingly applied to improve the process. Therefore, in this study, we propose a transformer-based fine-grained named entity recognition (NER) architecture for clinical information extraction. We collected 88 abdominopelvic sonography reports in free-text formats and annotated them based on our developed information schema. The text-to-text transfer transformer model (T5) and Scifive, a pre-trained domain-specific adaptation of the T5 model, were applied for fine-tuning to extract entities and relations and transform the input into a structured format. Our transformer-based model in this study outperformed previously applied approaches such as ANN and CNN models based on ROUGE-1, ROUGE-2, ROUGE-L, and BLEU scores of 0.816, 0.668, 0.528, and 0.743, respectively, while providing an interpretable structured report.

## Dataset

Our annotated [dataset](https://doi.org/10.5281/zenodo.7072374) used in the paper is hosted in this repository and in [Kaggle Datasets](https://www.kaggle.com/datasets/sarme77/reportql).

The data is structured as follows:

```
data/
├── trialReport
│   └── ReportQL
│       ├── Schemas
│       │   └── organs
│       │       └── simpleSchema.json
│       └── dataset
│           ├── test.csv
│           ├── train_orig.csv
│           └── training.csv
```

The `train_orig.csv` is our original training set. You can find our synthetic dataset and test set in `training.csv` and `test.csv` file.

Information schema used for annotating reports can be found in `simpleSchema.json`
