Area of Science:

  • Radiology
  • Medical Imaging
  • Oncology

Background:

  • Mammography is a key tool for breast cancer screening.
  • Dense breast tissue can obscure lesions, challenging mammographic interpretation.
  • Intravenous contrast agents can enhance lesion visibility in various imaging modalities.

Purpose of the Study:

  • To evaluate the efficacy of intravenous contrast material with full-field digital mammography for detecting and characterizing breast lesions.
  • To assess the potential of contrast-enhanced digital mammography as a diagnostic tool.

Main Methods:

  • Twenty-two women with suspected breast abnormalities underwent contrast-enhanced digital mammography.
  • Sequential imaging was performed after intravenous contrast agent injection.

  • Image processing involved registration and logarithmic subtraction; lesions were analyzed for enhancement presence, morphology, and kinetics.

    • Main Results:

    • Enhancement was observed in 8/10 patients with confirmed cancers.
    • No enhancement was seen in 7/12 lesions initially suspected as malignant but proven benign.
    • Lesion morphology generally correlated with pathology; enhancement kinetics were inconsistent but similar to MRI.

    Conclusions:

    • Contrast-enhanced digital mammography shows potential for identifying lesions in mammographically dense breasts.
    • This technique may aid in the diagnosis of breast cancer.
    • Further investigation is warranted to establish contrast-enhanced digital mammography as a reliable diagnostic tool.
