⚠️ WARNING: Look for /restricted/projectnb/batmanlab/shawn24/PhD and replace it with your own path. E.g, .src/codebase/breastclip/data/datasets/imagetext.py, change the json path

⚠️ WARNING: There is a plethora of pre-processing settings available for RSNA and VinDr Mammo datasets. We recommend using the pre-processing discussed in the following sections. We are not responsible for any discrepancies in the results due to different pre-processing settings. If you use the VinDr png dataset uploaded in kaggle, it is fully pre-processed. Else you can use the pre-processing scripts provided in the following sections.

⚠️ WARNING: If you find the punkt_tab error, run the following command in the python environment:

import nltk

nltk.download('punkt_tab')

FAQ

After going through the instruction, it is recommended to visit the following queries logged in the issues:

  • Issue-2 for any further clarification on pretraining.
  • Issue-10 for getting the embeddings.
  • Issue-6 for further clarification on the downstream tasks and corresponding datasets.
  • Issue-13 for setting up the baselines.
  • Issue-9 for problems related to BioClinincalBert from Hugging Face.

If we hear more queries, we may add a separate FAQs in the future.

Environment Setup

Use environment.yml to setup the environment.

git clone git@github.com:batmanlab/Mammo-CLIP.git
cd Mammo-CLIP
conda env create --name Mammo-CLIP -f environment.yml
conda activate Mammo-CLIP

Mammo-CLIP is implemented with following specification:

  • Python version: 3.8.18
  • PyTorch version: 2.2.2
  • CUDA version: 11.8

Data Download

Download the original versions VinDr and RSNA from the links for downstream evaluations:

For the PNG images converted from the original Dicom images, as mentioned in the preprocessing steps in the paper, refer to the following links:

To preprocess the dicom images directly, follow the instructions in the next section. If you downloaded the PNG images, skip the preprocessing steps.

Pre-processing images

Convert to png: RSNA

python ./src/preprocessing/preprocess_image_to_png_kaggle.py \
  --phase="test" \
  --base_folder="/restricted/projectnb/batmanlab/shawn24/PhD/RSNA_Breast_Imaging/Dataset/RSNA_Cancer_Detection"

convert to png: VinDr

python ./src/preprocessing/preprocess_image_to_png_vindr.py \
  --phase="test" \
  --base_folder="/restricted/projectnb/batmanlab/shawn24/PhD/RSNA_Breast_Imaging/Dataset/External/Vindr/vindr-mammo-a-large-scale-benchmark-dataset-for-computer-aided-detection-and-diagnosis-in-full-field-digital-mammography-1.0.0"

Data preparation for pretraining

Image-text dataset

  1. Our image-text dataset is an in-house dataset from UPMC. You can have your own image+text dataset where images are 2D mammograms and texts are radiology reports. If you have access to such dataset, follow the setup here. Extract the IMPRESSION and FINDINGS sections from the report and create a csv. The sample csv: upmc_dicom_consolidated_final_folds_BIRADS_num_1_report.csv

  2. Note the FINDINGS and IMPRESSION columns are used to generate the text for the image. The HISTORY, FINDINGS and IMPRESSION columns contains templated text due to privacy.

  3. Next run the following command to augment the text with upmc_dicom_consolidated_final_folds_BIRADS_num_1_report.csv file:

# input: upmc_dicom_consolidated_final_folds_BIRADS_num_1_report.csv
# output: clip_pretrain_100.csv

python ./src/codebase/augment_text.py \
  --dataset-path="/restricted/projectnb/batmanlab/shawn24/PhD/Mammo-CLIP/src/codebase/data_csv" \
  --csv-path="upmc_dicom_consolidated_final_folds_BIRADS_num_1_report.csv" \
  --dataset="upmc"

The augment_text.py script will do the preprocessing for the FINDINGS and IMPRESSION columns by converting them to lower case and removing punctuations. Look at the _split_report_into_segment_concat function in the script for more details.

  1. The csv file of the final image-text dataset should have the following format:
index patient_id laterality image view CC MLO text text_augment
0 patient_id laterality ('R' or 'L') List of all image_paths for patient_id-laterality combo List of views for patient_id-laterality combo (only 'CC' and 'MLO' are used) List of image paths for CC view for patient_id-laterality combo List of image paths for MLO view for patient_id-laterality combo List of [findings, impression] List of [augmented findings, augmented impression]
  1. The final sample csv file as the output of step3 is here: clip_pretrain_100.csv. clip_pretrain_100.csv is used for pretraining the image-text variant of Mammo-CLIP.

Image-label dataset

We use VinDr dataset as image-label dataset though it can be expanded to any such datasets. Make sure that every patient should have atleast one CC and MLO image per laterality. So if you are planning to use it in the pre-training setup, use the following notebook to preprocess the VinDr dataset:

./src/codebase/notebooks/preprocess-clip/VinDr.ipynb

When you download the VinDr dataset, you will get these two csv files: breast-level_annotations.csv and finding_annotations.csv . We preprocess the finding_annotations.csv file to get vindr_detection_v1_folds.csv . VinDr.ipynb notebook requires vindr_detection_v1_folds.csv file as input and generate clip_vindr_final.csv file.

Both clip_pretrain_100.csv and clip_vindr_final.csv files are used for pretraining the image-text and image-label variant of Mammo-CLIP.

The csv file of the final image-label (VinDr) dataset should have the following format:

index patient_id laterality image view CC MLO CC_FINDING MLO_FINDING
0 patient_id laterality ('R' or 'L') List of all image_paths for patient_id-laterality combo List of views for patient_id-laterality combo (only 'CC' and 'MLO' are used) List of image paths for CC view for patient_id-laterality combo, e.g, [CC_img ..] List of image paths for MLO view for patient_id-laterality combo, e.g, [MLO_img .. ] Findings per image per laterality for CC view (see below for the format) Findings per image per laterality for MLO view (see below for the format)

Explanation for CC_FINDING and MLO_FINDING Columns: In the above table, for the row, CC_FINDING can be expanded as:

[
  [+ve findings for CC_img if laterality of CC_img is R],
  [+ve findings for CC_img if laterality of CC_img is L],
  [-ve findings for CC_img if laterality of CC_img is R],
  [-ve findings for CC_img if laterality of CC_img is L],
]

As VinDr contains a single image per patient-laterality combo, we did n

Similarly, in the above table, for the row, MLO_FINDING can be expanded as:

[
  [+ve findings for MLO_img if laterality of MLO_img is R],
  [+ve findings for MLO_img if laterality of MLO_img is L],
  [-ve findings for MLO_img if laterality of MLO_img is R],
  [-ve findings for MLO_img if laterality of MLO_img is L],
]

Data preparation for downstream evaluation tasks

Use the following csv files as metadata for the downstream tasks (classification, detection, zero-shot):

Dataset CSV
VinDr vindr_detection_v1_folds.csv
RSNA train_folds.csv

For detection/localization tasks, we have included the coordinates of the resized bounding boxes of VinDr in the above csv file. Somebody interested in resizing the bounding boxes by themselves, run the following command with finding_annotations.csv file as input:

python ./src/preprocessing/preprocess_VinDr_detector.py

Mammo-CLIP checkpoints

Following are the pre-training checkpoints of Mammo-CLIP:

Model architecture Checkpoints (Google drive) Checkpoints (Hugging Face)
Best performance Efficient-Net B5 Efficient-Net B5
Lightweight Efficient-Net B2 Efficient-Net B2

We have also uploaded the downstream checkpoints for classification and localization (both linear probe and finetuning) with the image encoder of Efficient-Net B5 Mammo-CLIP for fold 0 here.

Pretraining Mammo-CLIP

For pretraining Efficient-Net B5 Mammo-CLIP with a single GPU, use the following command:

python ./src/codebase/train.py --config-name pre_train_b5_clip.yaml

For pretraining Efficient-Net B5 Mammo-CLIP with a 4 GPUs using pytorch-ddp, use the following command:

torchrun --nproc_per_node=4 ./src/codebase/train.py --config-name pre_train_b5_clip.yaml

All the yaml files for the config are found here.

Creating classifiers and detectors for downstream evaluations

  • For creating classifiers for downstream evaluations using the image encoder of Mammo-CLIP, use the class BreastClipClassifier in breast-clip-classifier.py file.
  • For creating detectors for downstream evaluations using the image encoder of Mammo-CLIP, use the function RetinaNet_efficientnet in detector_model.py file.

abstract="The lack of large and diverse training data on Computer-Aided Diagnosis (CAD) in breast cancer detection has been one of the concerns that impedes the adoption of the system. Recently, pre-training with large-scale image text datasets via Vision-Language models (VLM) (e.g., CLIP) partially addresses the issue of robustness and data efficiency in computer vision (CV). This paper proposes Mammo-CLIP, the first VLM pre-trained on a substantial amount of screening mammogram-report pairs, addressing the challenges of dataset diversity and size. Our experiments on two public datasets demonstrate strong performance in classifying and localizing various mammographic attributes crucial for breast cancer detection, showcasing data efficiency and robustness similar to CLIP in CV. We also propose Mammo-FActOR, a novel feature attribution method, to provide spatial interpretation of representation with sentence-level granularity within mammography reports.
