What is a neuraxis MRI?

What is a neuraxis MRI?

Gd-enhanced neuraxis MRI is a preferred radiographic method for establishing a diagnosis of NM. The findings indicative of NM include the leptomeningeal enhancement extending basal cisterns in the procumbent, nodal or massive manners, and intradural-enhancing nodules, especially in the cauda equina.

Where does the human neuraxis Bend?

Humans, as two-legged animals, have a bend in the neuraxis between the brain stem and the diencephalon, along with a bend in the neck, so that the eyes and the face are oriented forward.

What is the level of neuraxis?

What direction term refers to the front end of the neuraxis?

However, there is a major curve between the brain stem and forebrain, which is called the cephalic flexure. Because of this, the neuraxis starts in an inferior position—the end of the spinal cord—and ends in an anterior position, the front of the cerebrum.

What plane is the brain in?

Because the brain is a three dimensional structure, any location in the brain can be localized on three planes – the x, y and z planes. The brain is can be cut on any of these planes and are named the coronal plane, the horizontal plane or the sagittal plane.

What are brain flexures?

The cephalic flexure also known as the mesencephalic flexure, is the first flexure or bend that forms between the midbrain and hindbrain. The caudal part of the midbrain and the rostral part of the hindbrain makes up a mibrain-hindbrain boundary region known as the isthmic organizer.

Where is Neuroaxis?

The neuraxis or sometimes neuroaxis is the axis of the central nervous system. It denotes the direction in which the central nervous system lies. During embryological development, the neuraxis is bent by various flexures, contributing to the mature structure of the brain and spinal cord.

What is the Rostrocaudal axis?

Similarly, the term “caudal” is used more in embryology and only occasionally used in human anatomy. This is because the brain is situated at the superior part of the head whereas the nose is situated in the anterior part. Thus, the “rostrocaudal axis” refers to a C shape (see image).
