Fig. 5. From: 3D Morphometric Analysis of Human Fetal Cerebellar Development.

Linear dimensions of the cerebellum and vermis from 20 to 30 GW. The transverse cerebellar diameter (R2 = 0.95), vermis height (R2 = 0.91), and vermis anteroposterior diameter (R2 = 0.90) significantly increased linearly

Histogram of the age distribution of fetal MR scans. All 2-week periods include at least four scans. Gestational age is calculated from last menstrual period

Linear and exponential growth curves for cerebral and cerebellar volumes from 20 to 31 GW. All structures significantly increased in volume and exponential trajectories better described the growth for the cerebellum (linear R2 = 0.92, exponential R2 = 0.96) and hemispheres, but not the midsagittal vermis (linear R2 = 0.88, exponential R2 = 0.83)

Example of cerebellum linear dimensions and volumetric segmentation at 25 gestational weeks. a, b) The perimeter of the cerebellum was manually drawn then labeled as right hemisphere (blue), left hemisphere (red), and midsagittal vermis (yellow). c Transverse cerebellar diameter (TCD) was measured at the maximum distance in the coronal plane. d Vermis height (VH; solid line) and anterior–posterior diameter (VAP; dashed line) were measured on the midsagittal slice Cerebellum

Local curvature analysis of the cerebellar surface. a The mean curvature across all ages is overlaid on the average surface. Positive values (warm colors) express local convexity, and negative values (cool colors) indicate local concavity. Age-related changes in local curvature were tested for significance with multiple comparisons correction at p < 0.05 (|T| > 4.25). The last two columns show the full T maps with contours around the significant increases (b) and decreases (c) in convexity. Changes in curvature surrounding the inferior vermis are related to the formation of the paravermian fissure (arrow head)

A dedicated image analysis framework for the mapping of cerebellar surface morphology from in utero MRI. a Motion-corrected 3D MRI volumes of the fetal brain are manually segmented into right and left cerebellar hemispheres and cerebellar vermis. b Tissue maps extracted from manual segmentations are smoothed with a Gaussian kernel. c To account for the overall brain growth, the maps are linearly registered to a reference anatomy and then tessellated into triangular meshes to reconstruct the outer surface of the fetal cerebellum. d Local measurements of mean surface curvature are mapped onto a population-average cerebellar surface established via volumetric group-wise registration. e Statistical modeling is performed for each vertex of the population-average surface to detect local patterns of curvature change Cerebellum
