Keywords: Perfusion, Contrast Mechanisms, breast tumor; dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI)
Motivation: Breast MRI plays a vital role in early breast cancer screening, staging, and surgical guidance. The core technology used in breast MRI is DCE-MRI.
Goal(s): This study aims to assess the effectiveness of using the GRASP sequence in distinguishing highly malignant breast lesions.
Approach: We utilized the GRASP sequence, which offers high temporal resolution, to compare and analyze the microvascular characteristics of benign and malignant breast lesions.
Results: We found that Kep was significantly higher in malignant lesions compared to benign lesions, suggesting a potential relationship between the abundant blood supply and high wall permeability observed in malignancies.
Impact: The GRASP dynamic enhancement technique provides both morphological and hemodynamic characteristics of breast lesions, aiding in the differentiation of high-grade malignancies.
