Normal fetal brain at 24 weeks gestation. No mega cisterna magna or other posterior fossa abnormality.
Normal, gestation appropriate sulcation is shown. Note calcarine and parietooccipital sulci on medial aspect of hemispheres on coronal and axial images respectively. Sylvian fissure opercularization has progressed and early evidence of central sulcus noted on sagittal images. Normal vermis foliation is present on the midline sagittal spoiled gradient echo image. This is also a nice example of normal, five-layered lamination.
Sagittal acquisition somewhat oblique, but was the best possible.
