    High-resolution positron emission mammography (PEM) offers precise breast cancer detection, including early-stage and precursor lesions. This advanced imaging may eventually replace X-ray mammography due to its high accuracy and potential for personalized treatment.

    Area of Science:

    • Oncology
    • Medical Imaging
    • Radiology

    Background:

    • Current breast cancer detection methods face limitations in identifying early-stage and precursor lesions.
    • Accurate staging of intraductal breast cancer is crucial for effective surgical excision and treatment planning.
    • Assessing treatment response in ductal carcinoma in situ (DCIS) lacks objective, quantitative methods.

    Purpose of the Study:

    • To evaluate the potential of high-resolution positron emission mammography (PEM) for early breast cancer detection and translational research.
    • To highlight PEM's capability in imaging in situ breast cancers and precursor lesions.
    • To explore PEM's role in guiding surgical decisions, optimizing radiotherapy, and enabling personalized cancer therapy.

    Main Methods:

    • Utilizes the quantitative capabilities of positron emission tomography (PET) with millimeter resolution.

  • Focuses on imaging earliest in situ forms of breast cancer and precursor lesions.
  • Employs advanced imaging techniques for high-resolution breast tissue analysis.

    • Main Results:

    • PEM demonstrates high overall accuracy (sensitivity and specificity) in breast imaging.
    • The technology can image early in situ breast cancers and precursor lesions like atypical ductal hyperplasia.
    • PEM provides quantitative data crucial for assessing treatment response and guiding surgical interventions.

    Conclusions:

    • High-resolution PEM addresses clinical needs for early breast cancer detection and translational studies.
    • PEM's accuracy and potential for dose reduction suggest it may replace X-ray mammography.
    • Future applications include personalized therapy and surveillance of high-risk populations.
