Fig. 5. Spectroscopic photoacoustic (sPA) molecular imaging of a B7-H3 antibody-ICG conjugate (B7-H3-ICG) in normal mammary glands and glands containing DCIS.

Fig. 5

a Representative B-mode ultrasound (top) and sPA (bottom) images of murine mammary glands with either normal (left) or DCIS (right) tissues (red dashed circle) after injection with B7-H3 Ab-ICG. Scale bar = 2 mm. b Box plot of sPA molecular imaging signal (a.u.) distribution in normal mammary glands (n = 17, sPA = 3.2 ± 2.0 a.u.) and DCIS (n = 53, sPA = 22.7 ± 40.2 a.u.). Box plot follows Tukey rules. Glands containing DCIS show statistically significantly higher sPA molecular imaging signal (P < 0.05). c Receiver operating curve depicting the ability of B7-H3 expression imaged by sPA and B7-H3 Ab-ICG to differentiate between normal glands and glands containing DCIS (AUC = 0.93, 95% CI 0.86, 0.99).
