What anatomical structures are well seen with MRI  
         
 
 
 
     
 

BRAIN AND SPINAL CORD

The image on the left is an axial T2 MRI of the brain, including the orbits, and the image on the right is an axial T2 MRI of the spine.

The darker spinal cord is seen discretely, surrounded by the brighter subarachnoid fluid. The white dot in the center of the spinal cord is an abnormal fluid filled cavity, called a syrinx. The nucleus pulposis, the fluid component of the intervertebral disc, can be differentiated from the anulus fibrosis, the outer dark fibrous band of the intervertebral disc.

These images demonstrate how exquisitely the internal anatomy of the brain and spinal cord is seen. No other imaging modality can compare with MRI for imaging the central nervous system.
