Multiple sclerosis (MS) is a disease that affects the central nervous system, particularly the nerves. If you or someone you love has been asked to get an MRI (magnetic resonance imaging) scan due to a potential MS diagnosis, you may have many questions about the procedure. Below is a guide to how this type of scan assists with the detection and monitoring of multiple sclerosis.

How Do MRI Scans Detect MS?

General Diagnosis

MRI scans use a combination of magnetic and radio waves to develop images that detect water in bodily tissues. Nerves repel water, but if they’re damaged by MS, they have elevated water contents, showing up as abnormal spots on a scan.

Getting an MRI scan is the most precise and noninvasive way to detect these changes in the brain and spinal cord.

Clinically Isolated Syndrome (CIS)

An isolated period of destruction of the nerves lasting for at least 24 hours is called clinically isolated syndrome (CIS). An MRI scan identifies this event and determines how it affects someone’s risk of developing MS in the future.

If the scan detects lesions similar to those caused by MS, a doctor may prescribe the patient medication to prevent or delay another attack. If no lesions are present, the risk of MS is lower, and treatment may not be needed unless the person experiences a second episode.

How Do Doctors Use MRI Scans for Those Diagnosed With MS?

Once someone is diagnosed with MS, doctors continue to use MRI scans to provide care. Scans detect changes in the brain and spinal cord, allowing the physician to assess how quickly the disease is progressing.

Doctors use the images produced and all symptom reports to determine if the current treatment is effective or should be changed. Since treatment for MS consists of managing symptoms and slowing progression, monitoring changes is key to a successful treatment.
