FIGURE 7.

3D morphology and section images of placenta villi with FGR via OCT. (a) Top view of 3D OCT morphology shows placenta with FGR has relatively small volume terminal villi and the tree structure of the placenta with FGR is different than that of the normal placenta, with fewer villi branches and shorter intermediate villi. Representative intermediate villi with branched terminal villi (orange arrow). (b) A representative OCT en‐face image of placental villi with FGR. (c) A representative rescaled B‐scan image of placental villi corresponding to the position indicated by green dashed lines in (a). (d) A representative rescaled B‐scan section image of placental villi corresponding to the position indicated by blue dashed lines in (a). All scale bars are 500 μm. FGR, fetal growth restriction; OCT, optical coherence tomography
