Accepted Answer

Symptoms : Symptoms of numbness of the entire body from the neck down can have many causes.  Of these many causes, a process involving part of the spinal cord in the neck would be the most concerning.  Spinal cord problems could include syringomyelia or transverse myelitis, which can sometimes cause sensory problems without weakness.

Numbness from the neck down can also be caused by psychogenic (also known as somatoform, or "stress induced") problems, which can often be most challenging for the physician and patient to resolve.  Psychogenic numbness can increase the chance of diagnosing something that is not actually there (leading to unnecessary and potentially dangerous tests and treatments) or lead to missing a diagnosis of an organic problem (potentially delaying appropriate treatment).

A stroke in the brain would probably not cause symptoms of isolated numbness of the entire body from the neck down.

Problems involving the spinal cord in the neck can be seen using an MRI of the cervical spine, usually done with and without gadolinium contrast.

Question 9

how much for a ct scan vs mri?

Accepted Answer

About the same: There were appreciable differences in previous years but most facilities charge about $800-1000 for a ct and about $1200-1500 for an mri.  It can vary greatly depending on where you have it done.
Call ahead and try to negotiate a price.

Question 10

which is safe and mri or ct scan?

Accepted Answer

Both are safe.....: Mri has no ionizing radiation, thus there is no risk of radiation induced cancer. However, MRI is not for everyone. If you are claustrophobic, have a heart pacer, or have shrapnel you may not be able to have an mri. Ct does have radiation, but the dose is very small and in most cases less than you are exposed to just by living on earth for one year. You, your doc and radiologist should decide.
