Hi,
Spine consists of vertebrae and intervertebral discs in between along with muscles, ligaments, nerves and blood vessels.
Spinal cord continuous from the distal end of brain run through the spine and supply the rest of the body. Each vertebra has anterior body and posterior laminae with vertebral foramen in the center. Between two vertebrae is the fibrous intervertebral disc which helps in movements of spine and acts as a
shock absorber. Spinal cord runs through the vertebral foramen and it is covered by meningeal layer called
thecal sac with
cerebrospinal fluid inside it. Spinal nerves arise from the spinal cord with root passes through the intervertebral foramen.
Neuroforaminal narrowing indicates that the narrowing of the foramen through which the spinal nerves passes. This condition may progress to cause spinal nerve compression which causes
neuralgia. Intervertebral disc may bulge out and compress the thecal sac with the structure inside it.
Hemangioma is
blood vessel tumor formed from the capillaries and venous system. Retrolistheis is the condition in which the vertebral move backwards from the normal alignment that is behind the discs. T1 and T2 images indicates fatty tissues and fatty tissue and water respectively.
Take care. Hope I have answered your question. Let me know if I can assist you further.
