Hemoglobin map construction using the optical breast imaging system. Representative images include a palpable 38-mm mucinous carcinoma on the left breast in a 56-year-old woman. (a) Optical measurements comprising a grid map over tumor (7 × 7 points, 1-cm pitch) and normal breast tissue (5 × 5 points, 1-cm pitch) are taken using a handheld probe. (b) Ultrasound (US)-guided breast imaging system with time-resolved diffuse optical spectroscopy (DOS). (c) The images present distribution of total hemoglobin (tHb) and tissue oxygen saturation (stO2) concentrations on both breasts. (d) A mediolateral oblique mammogram shows a round circumscribed mass (arrowhead) in the subareolar area. (e) A sagittal US image obtained at the 4 o'clock position in the left breast shows a lobulated hypoechoic shadowing mass (arrowhead). (f) Dynamic contrast-enhanced (DCE) MRI shows a solitary intensely enhancing mass (arrowhead) in the lower outer quadrant of the left breast. L, left; R, right.
