PromptMRG

Code of AAAI 2024 paper: "PromptMRG: Diagnosis-Driven Prompts for Medical Report Generation".

Installation

1. Clone this repository.

   git clone https://github.com/jhb86253817/PromptMRG.git

2. Create a new conda environment.

   conda create -n promptmrg python=3.10
   conda activate promptmrg

3. Install the dependencies in requirements.txt.

   pip install -r requirements.txt

   Datasets Preparation

   • MIMIC-CXR: The images can be downloaded from either physionet or R2Gen. The annotation file can be downloaded from the Google Drive. Additionally, you need to download clip_text_features.json from here, the extracted text features of the training database via MIMIC pretrained CLIP. Put all these under folder data/mimic_cxr/.
   • IU-Xray: The images can be downloaded from R2Gen and the annotation file can be downloaded from the Google Drive. Put both images and annotation under folder data/iu_xray/.

Moreover, you need to download the chexbert.pth from here for evaluating clinical efficacy and put it under checkpoints/stanford/chexbert/.

You will have the following structure:

PromptMRG
|--data
   |--mimic_cxr
      |--base_probs.json
      |--clip_text_features.json
      |--mimic_annotation_promptmrg.json
      |--images
         |--p10
         |--p11
         ...
   |--iu_xray
      |--iu_annotation_promptmrg.json
      |--images
         |--CXR1000_IM-0003
         |--CXR1001_IM-0004
         ...
|--checkpoints
   |--stanford
      |--chexbert
         |--chexbert.pth
...

Training

• To train a model by yourself, run bash train_mimic_cxr.sh to train a model on MIMIC-CXR.
• Alternatively, you can download a trained model weight from here. Note that this model weight was trained with images from R2Gen. If you use images processed by yourself, you may obtain degraded performance with this weight. In this case, you need to train a model by yourself.

  Testing

  Run bash test_mimic_cxr.sh to test a trained model on MIMIC-CXR and bash test_iu_xray.sh for IU-Xray.
