Examples of generated ROIs delineating the primary lesion and ipsilateral axillary SLN in MRI images. Panels (a, b, e, and f) show a 59-year-old patient with NAT-low, featuring the primary lesion (a, e) and ipsilateral axillary SLN (b, f). Panels (c, d, g, and h) depict a 41-year-old patient with NAT-high, illustrating the primary lesion (c, g) and SLN (d, h). The yellow regions represent manually delineated tumor ROIs covering the entire tumor, while the red regions indicate peritumoral ROIs. The green regions show manually delineated ROIs of the ipsilateral axillary SLN
