Comparison of Fetal Cerebellum and Cisterna Magna Length by 2D and 3D Ultrasonography between 18 and 24 Weeks of Pregnancy
Figure 1
(a) Three-dimensional scan at the pattern plan level of measurement for the transverse cerebellar and anterior-posterior cisterna magna diameter (thalamus, cerebellar hemispheres, cisterna magna, cavum septum pellucidum, the occipital bone, and nuchal fold) encompassing the entire fetal skull (ROI-region of interest). (b) Multiplanar mode: axial (top right), sagittal (lower right), and coronal (top left). (c) Multislice view: arrangement (two rows and three columns), with slice thickness cut of 0.5 mm. (d) Adjacent sequential images, showing plan above the cerebellum (in red).
