Our new MRI is here!
Magnetic Resonance Imaging

What is MRI?

Mason General Hospital's Diagnostic Imaging Department has Magnetic Resonance Imaging (MRI) available. MRI technology combines a powerful magnet, radio waves, and a computer to produce high-quality images that assist physicians in assessing a patient’s condition. It differs from both the x-ray and CT scan because it uses radio waves to pass through the body. This provides exceptional pictures showing soft body tissue in great detail.

There are no known side effects and the unit uses no harmful radiation. Nearly any body part may be evaluated from nearly any angle.

New "Open" MRI

Our new, Panorama High Field Open MRI is now in service! The MRI is spacious and comfortable, boasting an almost 360-degree opening, so that anyone with claustrophobia can be scanned in comfort. No longer will patients have to use the mobile MRI that was located outside of the building, as this new, state-of-the-art MRI is now located inside the Hospital for convenience and privacy.

With your physician’s referral, call (360) 427-9590 to schedule your scan.

Preparing for your MRI

Your MRI requires very little effort on your part. It's a simple process, but preparation is essential! Here's what you need to know:

When Your Appointment Is Scheduled

Before we schedule you for an MRI exam, we will ask a number of questions. Your answers will help us identify any current conditions that may make it unsafe for your MRI. You will need to inform us if:

  • you are pregnant
  • you've ever had surgery
  • you're on pain medication
  • you're claustrophobic
  • you have an incident of metal to your eyes
  • you have cardiac valve replacements or a pacemaker, bone or joint replacements, or aneurysm clips, or cardiac stents

These conditions may not exclude you from having an MRI scan, but they'll be important determining factors. Please be prepared to provide information on your insurance and medical history. We'll be happy to discuss all aspects of your MRI exam and answer any remaining questions you may have at that time.

The Day Of Your MRI

Your first task for this day is simple: Relax. Typically you can eat normally and take prescribed medication the day of your MRI exam. If you are having an examination of the abdominal area your physician may request that you abstain from eating prior to your scan. For your personal comfort and enjoyment, you may like to have someone accompany you. He or she may be able to sit and talk with you during the exam. We recommend you wear comfortable clothing, free of snaps and zippers. Since rings, watches, and earrings are all metal, and thus, could interfere with your scan, please leave these items at home.

When You Arrive

Plan on arriving 30 minutes ahead of your scheduled appointment. Your technologist and/or patient care associate will discuss the procedure with you at that time.

Starting The Scan

To begin the examination, a technologist will help you lie down on a padded table. You will be positioned so that the part of your body to be examined lies in the center of the machine. A coil may be attached to the part of the body to be scanned, and your physician may request that a contrast agent be injected (to enhance the images). The table will then slide into the center of the MRI machine.

During The Scan

You will be asked to hold still for short periods of time while the scan is in progress. Expect to hear a loud knocking noise from the machine as the pictures are taken. The technologist who will be monitoring the exam from an adjoining room will be able to hear you and talk with you at all times.

After The Exam

When the scan is complete, your technologist will help you leave the table. In most cases, you may return to your normal activities immediately after the procedure.

With The Radiologist

A radiologist who is a specialist in MRI will then interpret your images. The radiologist will make an expert interpretation of the image and prepare a written report to be sent to your referring physician.

With Your Physician

Your personal doctor will review the findings of the MRI in the context of your overall condition and discuss them with you. Based on the interpretation and findings, you and your doctor will plan your treatment. Your doctor may choose to monitor your progress with another MRI scan.
