Comparative Diagnostic Performance of Breast MRI and PET/CT in Axillary Nodal Staging of Breast Cancer

Ultrasonography, often combined with image-guided biopsy, remains the primary modality for initial axillary assessment. 6However, cross-sectional imaging techniques provide additional structural and functional information that may refine nodal evaluation.Breast magnetic resonance imaging (MRI) enables detailed morphological characterization of lymph nodes, including cortical thickening, loss of fatty hilum, and abnormal contrast enhancement
