Abstract
In this paper, we introduce IHRRB-DINO, an advanced model designed to assist radiologists in effectively detecting breast masses in mammogram images. This tool is specifically engineered to highlight high-risk regions, enhancing the capability of radiologists in identifying breast masses for more accurate and efficient assessments. Our approach incorporates a novel technique that employs Data-Driven Instance Noise (DINO) for Object Localization, which significantly improves breast mass localization. This method is augmented by data augmentation using instance-level noise during the training phase, focusing on refining the model’s proficiency in precisely localizing breast masses in mammographic images. Rigorous testing and validation conducted on the BI-RADS dataset using our model, especially with the Swin-L backbone, have demonstrated promising results. We achieved an Average Precision (AP) of 46.96, indicating a substantial improvement in the accuracy and consistency of breast cancer (BC) detection and localization. These results underscore the potential of IHRRB-DINO in contributing to the advancements in computer-aided diagnosis systems for breast cancer, marking a significant stride in the field of medical imaging technology.

Review #2
- Please describe the contribution of the paper
This manuscript introduces a vision transformer model for breast mass detection in mammographic images.
- Please list the main strengths of the paper; you should write about a novel formulation, an original way to use data, demonstration of clinical feasibility, a novel application, a particularly strong evaluation, or anything else that is a strong aspect of this work. Please provide details, for instance, if a method is novel, explain what aspect is novel and why this is interesting.
1) Highly significant research topic. 2) Use of vision transformers enhances novelty.
- Please list the main weaknesses of the paper. Please provide details, for instance, if you think a method is not novel, explain why and provide a reference to prior work.
1) Potential data leakage in model evaluation - unclear if data splits were at the patient/image/mass level. Given that each mammographic exam contains multiple views, a mass may be visible in more than one view, and an exam may contain more than one masses, the way data was split is critical. 2) Limited reproducibility given that code is/will not be provided and in-house data was used. 3) Poor description of in-house data and respective data curation steps. There are various publicly available datasets in TCIA and beyond that could be used for this detection task. 4) Without standard deviations or confidence intervals, and p-values for comparisons, the statistical significance in the comparisons shown in Tables 1-2 is unclear. 5) Although several tools for breast mass detection are currently available, no comparisons with previous tools are reported. 6) The use of 2D versus 3D mammograms is a limitation that needs to be acknowledged.

Dataset descriptions remain poor, limiting the ability to fully evaluate the reported results, as well as the study’s reproducibility.
Standard deviations or confidence intervals are essential for the reported comparisons (Tables 1-2). Given the abundancy in available tools for breast mass detection, lack of comparisons with any of those is a major limitation.

Author Feedback
Response to Reviewer #1 Concern on Data Leakage: Reviewer #1 highlighted the criticality of data splits due to the multiple views and masses in mammographic exams. We confirm that our dataset was split at the patient level, ensuring that all images, views, and masses associated with a single patient were contained within the same subset, thus effectively preventing data leakage and maintaining the integrity of the model’s evaluation. Reproducibility and Data Access: Our study utilises in-house data, and we are committed to providing access to this data and the computational code upon reasonable request. This approach maintains confidentiality while upholding transparency necessary for scientific validation.
Data Description: We curated our dataset to ensure high quality and control, processed according to BI-RADS standards by expert radiologists. A more detailed account of our data collection, cleaning, and ROI extraction was indeed included in our paper to provide clarity on our rigorous data management. Statistical Analysis Clarity: We performed T-tests to assess the statistical significance of our model comparisons, with p-values such as 1.22×10^−12 for the IHRRB-DINO vs. CAM with Resnet50 indicating significant differences. These details underscore our commitment to rigorous statistical evaluation. Limitations in Technology Used: We acknowledge the use of 2D over 3D mammograms due to page constraints, and will ensure to address this discussion more thoroughly in future discussions to provide clarity. Combined Response to Reviewers 4 and #3 Explanation of CDN and Noise Addition: Both reviewers noted the need for a clearer explanation of CDN and our noise addition strategy. CDN is defined by two hyper-parameters, lambda_1 and lambda_2, which control the noise scale for positive and negative queries, enhancing the model’s accuracy. This bifurcation is critical, as positive queries aim to reconstruct ground truth boxes, while negative queries predict “no object,” helping to refine model training against irrelevant anchors. Evidence of DINO’s Effectiveness: Questions regarding the proof of DINO’s impact on model performance were addressed by detailed comparisons in our manuscript. Results from our tests, such as a T-statistic of a p-value of 1.59×10^−17 comparing IHRRB-DINO vs. ACOL with Inception v3, demonstrate significant improvements and validate DINO’s efficacy. Response to Reviewer #4 Clarity and Novelty in Methodology: Reviewer #4 raised concerns about the clarity around the DINO component and its naming, which might be confused with a known self-supervised learning method. DINO, in our context, stands for Data-Driven Instance Noise, a unique adaptation for object localization in breast mass detection. It enhances the model by introducing instance-level noise during the training phase, significantly improving detection accuracy. Baseline Comparisons: Our study’s primary objective was to explore the impact of integrating various pretrained models(swin-l, … etc) with our novel approach. We believe this focus allows us to contribute valuable insights into the potential enhancements these models can bring to breast mass detection methodologies. While we recognise the merit in comparing with existing tools, our intent was not to establish superiority but to highlight how pre-trained models can be effectively adapted within our framework to improve detection capabilities. Conclusion The comments from all reviewers have been invaluable in refining our presentation and explanations of complex methodologies. We have addressed each point raised, ensuring that our research contributions are clear and well-supported by empirical evidence. The discussions on CDN, data handling, and statistical validations are aimed at providing a comprehensive understanding of our work’s robustness and innovation.

This paper studies an important topic of mammogram image diagnosis, which has good clinical needs and is interesting to MICCAI community. The used dataset is of large-scale. Major concerns come from improvement on paper writing, details about implementation and statistical testing. In the rebuttal, the authors clarified that they used in-house data, and the authors are committed to providing access to this data and the computational code upon reasonable request. The authors also provided reasonable feedback to other comments. This meta reviewer considers that the major concerns could be mostly addressed through editing of the manuscript. The value of the work relies on the dataset to be released upon request from the scientific community.
