UHFUS Characterization of Normal Lymphatic Anatomy

This is a prospective pilot study of breast cancer patients undergoing axillary lymph node dissection (ALND) or sentinel lymph node biopsy (SLNB). Participants will undergo ultra-high frequency ultrasound (UHFUS) imaging with indocyanine green (ICG) dye to map lymphatic channels between the wrist and elbow to investigate normal lymphatic anatomy in patients with breast cancer.
