Normal Anatomy
Note how the fornix (Latin, “arch” or “vault”) is more easily seen as a paired structure on the T2-weighted axial magnetic resonance image (upper radiology image), compared with the fornix as seen in the Chapter 3 images focusing on the basal ganglia and thalami. The fornix is a C -shaped bundle of axons in the brain and carries signals from the hippocampus to the hypothalamus.

Normal Anatomy
The architecture of the dentate nucleus and cornu ammonis (hippocampus) is not well defined on axial magnetic resonance imaging. Asymmetry and abnormal signal are much better appreciated on coronal MR images.
