    Dynamic contrast-enhanced MRI (DCE-MRI) is the most sensitive imaging modality for breast cancer detection.

  • 2

    Background parenchymal enhancement (BPE) can mask or mimic suspicious lesions on DCE-MRI, complicating diagnosis.

  • 3

    BPE varies with menstrual cycle and is influenced by physiological factors, including hormone levels and vascular density.

  • 4

    The study employed a region-of-interest (ROI) approach to assess the impact of BPE on breast lesion detection.

  • 5

    Results indicated that while moderate to marked BPE may increase abnormal interpretation rates, it does not significantly affect diagnostic performance.
