    Area of Science:

    • Biomedical Engineering
    • Parasitology
    • Computational Pathology

    Background:

    • Chagas disease, caused by Trypanosoma cruzi (T. cruzi), often progresses unnoticed until significant myocardial damage occurs.
    • Histopathological analysis of endomyocardium biopsies for T. cruzi amastigotes is time-consuming and subjective, leading to potential diagnostic errors.

    Purpose of the Study:

    • To develop and evaluate a deep learning-based method for automated detection of T. cruzi amastigotes in histopathological images.
    • To improve the efficiency and objectivity of Chagas disease diagnosis using artificial intelligence.

    Main Methods:

    • Implementation and training of a U-Net convolutional neural network architecture from scratch.
    • Utilizing histopathological images from endomyocardium biopsies in an experimental murine model of Chagas disease.

    Main Results:

    • The deep learning model achieved a high accuracy of 99.19%.
    • A Jaccard index of 49.43% was obtained, indicating the model's effectiveness in segmenting amastigote nests.
    • The results demonstrate the potential of the approach for reliable amastigote detection.

    Conclusions:

    • The proposed deep learning method shows promise as an automated tool for detecting T. cruzi amastigotes in histopathological images.
    • This approach can significantly aid in the analysis and diagnosis of Chagas disease, potentially leading to earlier intervention.
