Fig. 5: 3D volumetric photoacoustic imaging placental response to vasodilators.
From: In vivo noninvasive systemic myography of acute systemic vasoactivity in female pregnant mice
Representative 3D volumetric image of placenta indicating umbilical cord (um), spiral artery (Sp), and fetal side of the placenta (fs) in response to sildenafil (a) and G-1 (b) at different time points. c Scatter plot of increase in placental photoacoustic (PA) signal intensity as a measure of blood volume from pre-injection volume at 30 min post-injection with mean and standard deviation (G-1, Sildenafil: n = 8 mice/group, PBS: n = 7 mice). The color bar represents the normalized photoacoustic signal intensity. Source data are provided as a Source Data file.
