For the first assessment and screening of breast cancer, mammography is still the most used imaging modality. Depending on positioning and technique, the axillary region, especially the lower axilla, could be evaluated and it is possible to see some level I axillary lymph nodes on mediolateral oblique (MLO) images. Increased nodal density, loss of fatty hilum, cortical thickness, or asymmetric large nodes are all signs of suspicion. Mammography has a limited field of view which limits its sensitivity for a thorough axillary assessment. Because of this, mammography by itself is not enough to accurately assess axillary region (Wang et al., Clin Breast Cancer. 24:e51–e60, 2024; Teixeira et al., RB Imagem, 2024).

摘要

For the first assessment and screening of breast cancer, mammography is still the most used imaging modality. Depending on positioning and technique, the axillary region, especially the lower axilla, could be evaluated and it is possible to see some level I axillary lymph nodes on mediolateral oblique (MLO) images. Increased nodal density, loss of fatty hilum, cortical thickness, or asymmetric large nodes are all signs of suspicion. Mammography has a limited field of view which limits its sensitivity for a thorough axillary assessment. Because of this, mammography by itself is not enough to accurately assess axillary region (Wang et al., Clin Breast Cancer. 24:e51–e60, 2024; Teixeira et al., RB Imagem, 2024).
