Figures
- Fig 1.
Segmentation of the brain structures with Amira 5.2.2. A, segmentation on the axial plane. B, Segmentation on the coronal plane.
- Fig 2.
Length measurements of the lateral ventricle. Arrows indicate the length. A, LTAP. B, LAPP. C, LPH. D, LCI. E, LHCP. F, LBIH.
- Fig 3.
Measurement of the calcarine sulcus. A, The depth of the calcarine sulcus (axial plane). B, The depth of the calcarine sulcus (coronal plane). C, The length of the calcarine sulcus (sagittal plane). D and E, The measurements of the depth and the length in the calcarine sulcus. The blue line shows the length of the sulcus. The red line shows the depth of the sulcus.
- Fig 4.
The morphologic evolution of fetal lateral ventricles at 14–31 weeks. ah indicates anterior horn; ph, posterior horn; ih, inferior horn; cp, central part; GW, gestational weeks.
- Fig 5.
Volume measurements of the lateral ventricles. L-LV indicates the left lateral ventricle volume; R-LV, right lateral ventricle volume; T-LV, total lateral ventricle volume; GA, gestational age.
- Fig 6.
Quantitative measurements of the lateral ventricles.
- Fig 7.
The depth and length of the calcarine sulcus. A, The depth of the calcarine sulcus. B, The length of the calcarine sulcus. C, The mean depth of the calcarine sulcus. D, The mean length of the calcarine sulcus.
- Fig 8.
The location of the calcarine sulcus in 3D space: superior view (A1, B1, C1), posterior view (A2, B2, C2), lateral view (A3, B3, C3). A, Twenty-one GW (A1, A2, A3). B, Thirty-one GW (B1, B2, B3). C, Thirty-five GW (C1, C2, C3). The left lateral ventricle is green, the right lateral ventricle is red, and the calcarine sulcus is pink. GW indicates gestational weeks.
- Fig 9.
The correlation between the LPH and the depth and length of the calcarine sulcus.
