    Dedicated breast CT scans with contrast enhancement offer superior diagnosis for benign and malignant breast diseases, especially in dense or fibrocystic breasts, detecting early cancers mammography may miss.

    Area of Science:

    • Radiology
    • Oncology
    • Medical Imaging

    Background:

    • Mammography, thermography, and physical exams have limitations in diagnosing breast diseases, particularly in dense or fibrocystic breast tissue.
    • Early detection of breast cancer is crucial for effective treatment and improved patient outcomes.

    Purpose of the Study:

    • To evaluate the diagnostic efficacy of a dedicated breast CT scanner with contrast enhancement compared to conventional methods.
    • To assess the capability of breast CT in detecting early-stage breast cancers and differentiating benign from malignant lesions.

    Main Methods:

    • Utilized a dedicated breast CT scanner (General Electric CT/M) with a contrast medium enhancement technique.
    • Compared CT findings with mammography, thermography, and physical examination results.

  • Evaluated the ability to identify morphologic changes and altered iodine pools in mammary tissues.

    • Main Results:

    • Breast CT demonstrated superiority over mammography, thermography, and physical examination in diagnosing both benign and malignant breast diseases.
    • CT successfully identified unsuspected early-stage carcinomas and differentiated precancerous lesions from fibrocystic disease.
    • CT provided definitive diagnostic help in inconclusive cases, influencing surgical decisions and potentially preventing unnecessary biopsies.
    • The technique accurately depicted morphologic changes and altered iodine distribution in breast tissues.

    Conclusions:

    • Dedicated breast CT with contrast enhancement is a highly effective tool for diagnosing breast diseases, particularly in challenging breast tissue types.
    • Breast CT offers significant advantages in early cancer detection, lesion characterization, and guiding clinical management.
    • This imaging modality provides valuable insights into both structural and functional aspects of breast tissue, including iodine uptake.
