Spinal Cord: http://www.nature.com/sc/index.html
The brain and spinal cord together make up the central nervous system (CNS).
The spinal cord begins at the occipital bone and extends down to the space between the first and second lumbar vertebrae; it does not extend the entire length of the vertebral column. It is around 45 cm (18 in) in men and around 43 cm (17 in) long in women. Also, the spinal cord has a varying width, ranging from 1/2 inch thick in the cervical and lumbar regions to 1/4 inch thick in the thoracic area. The enclosing bony vertebral column protects the relatively shorter spinal cord.
The spinal cord functions primarily in the transmission of neural signals between the brain and the rest of the body but also contains neural circuits that can independently control numerous reflexes and central pattern generators. The spinal cord has three major functions: as a conduit for motor information, which travels down the spinal cord, as a conduit for sensory information in the reverse direction, and finally as a center for coordinating certain reflexes.
see Spinal cord ischemia.
The spinal cord is poorly visualized on CT images but is well visualized in MRI images. However, implants used for spinal stabilization can produce artifacts on the MRI images which can interfere with identification of the cord. CT myelography in conjunction with CT simulation helps to clearly delineate the cord.
CT myelogram in conjunction with CT simulation is particularly useful in cases where the tumor margin is very close to the cord and spinal implants are causing distortion of magnetic resonance images 1).
Vascular Anatomy of the Spinal Cord: Radioanatomy as the Key to Diagnosis and TreatmentVascular Anatomy of the Spinal Cord: Radioanatomy as the Key to Diagnosis and Treatment By Armin K. Thron
This book systematically describes the angioarchitecture of the spinal cord. Microradiographs of superficial and intrinsic arterial supply and venous drainage patterns provide the anatomical basis needed to understand spinal vascular disorders. These post mortem studies are supplemented by clinical spinal angiographies and case studies.
Rapid advances in imaging technology have facilitated the solution of many diagnostic problems concerning diseases of the spine and spinal cord. But this is less true for vascular diseases of the spinal cord or diseases secondarily involving them. Furthermore, safely using interventional procedures or open surgery still requires a profound knowledge of the vascular anatomy involved. Accordingly, a growing demand for training in this special field has become evident over the last 25 years, making improvement of this knowledge in all Neuro-Specialities dealing with diagnostic and therapeutic problems of spinal disorders a highly desirable goal.
