Figure 3.

Two cases of breast cancer with positive and negative lymph node axillary involvement at definitive surgery, respectively. The first (a–c) represented by a 32 mm mass, in 56yo patient with TN CDI tumor characterized by spiculated margins, heterogeneous enhancement with a necrotic core and a signal/intensity curve type 3 at MRI exam. The second (d–f) is a 13 mm nodule, in a 61 yo patient, LUMINAL A CDI, characterized by irregular margins, heterogeneous enhancement and a signal/intensity curve type 3. The segmentation has been performed in the axial image (a,d), following the margins and including the spicule characterized by contrast-enhancement. The segmentation was then optimized in the sagittal (b,e) and coronal (c,f) planes, avoiding the darker part representing the necrosis and the vessels.
