MRI Q & A

How does MRI work?

Magnetic resonance imaging uses a magnetic field and radio waves to produce three-dimensional images of the structures in your body.

The MRI scanner creates a magnetic field around your body that pulls atomic particles (in cells) into alignment. Then the scanner releases radiofrequency (RF) waves that move through your body and push the same particles.

After the RF waves stop, the scanner picks up movement as the particles realign with the magnetic field. A computer translates the way they move into highly detailed images.

Why do I need an MRI?

Your physician may order an MRI to get images of your bones, joints, and soft tissues. However, MRI is a preferred imaging technique for soft tissues, such as nerves, blood vessels, ligaments, tendons, spinal discs, and muscles.

An MRI helps your physician diagnose numerous conditions, including:

  • Herniated discs
  • Degenerative disc disease
  • Spinal cord injuries
  • Spine and brain tumors
  • Brain aneurysms
  • Traumatic brain injuries
  • Heart disease
  • Liver disease
  • Inflammatory bowel disease
  • Shoulder injuries
  • Knee injuries
  • Arthritis

The details produced by MRI can reveal conditions like arthritis and tumors at the earliest possible stage. 

What type of MRI might I receive?

 All County Radiology has today’s most advanced MRI scanners, including open MRI, high-field open MRI, and 3T MRI. Here’s what that means: 

High-field open and open MRI

High-field and open are two separate qualities in an MRI scanner that make a dramatic difference to your experience and the image produced.

MRI scanners have different magnet strengths, called field strength. More powerful magnets produce better-quality images and reduce the time it takes to complete the scan. High-field MRIs are one of the most powerful magnets available.

There are two basic types of MRI scanners: open and closed. A closed scanner completely surrounds your body, making it hard for many people to tolerate, especially if they’re claustrophobic.

By comparison, an open MRI uses flat magnets. When lying on the table, you have one below you and one above you, but the sides are open, and there’s a lot of space between the magnets. The openness makes it easy for most people to tolerate.

3T MRI

The scanner’s magnet strength is measured in a metric system unit called Tesla (T). A 3T magnet is the next strongest after a high-field magnet and one of the highest fields currently available.

A 3T MRI takes better images of organs and soft tissues and is often used to create images of the brain, spine, joints, bone marrow, and blood vessels.

The 3T MRI is also compatible with SpinTech MRI software. All County Radiology uses this innovative software for advanced brain imaging that diagnoses traumatic brain injuries, Alzheimer’s disease, Parkinson’s disease, and many other neurological disorders.
