Ventricles and CSF Cisterns Axial 1 Normal Anatomy The ventricular system is located deep within the brain and is filled with cerebrospinal fluid (CSF). The normal appearance of CSF on magnetic resonance images is that of water. This axial MR…
Cranial Nerve I Axial 1 Normal Anatomy The olfactory nerve, or cranial nerve (CN) I, is the first of 12 cranial nerves and provides innervation for the sense of smell. CN I can often be seen on axial magnetic resonance…
Limbic System Axial 1 Limbic System Axial 1 Limbic System Axial 2 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),…
Thalamus and Basal Ganglia Axial 1 Normal Anatomy The centrum semiovale, corona radiata, and internal capsules are all continuous white matter tracts. The centrum semiovale is the white matter deep to the gray matter on the surface of the brain…
Brain Axial 1 Normal Anatomy Named after the French anatomist Paulin Trolard (1842–1910) and also known as the superior anastomotic vein, the vein of Trolard is the largest cortical vein at the convexity (see also Brain Coronal 15 ). The…

Hypopharynx, Larynx, and Infrahyoid Neck Axial 1 Diagnostic Consideration Axial 1 on the next page shows both a T2-weighted sequence (upper image) and a T1-weighted image (lower). Note that cerebrospinal fluid (CSF) around the spinal cord is bright on T2-weighted…
Oral Cavity, Pharynx, and Suprahyoid Neck Axial 1 Normal Anatomy Note the enhancement of the mucosal surfaces of the aerodigestive tract on the lower magnetic resonance (MR) image in Axial 1 after gadolinium contrast administration. The subcutaneous adipose tissue and…
