Q & A about MRI

What exactly is MRI?

MRI stands for Magnetic Resonance Imaging. Without using traditional X-ray imaging, MRI allows doctors to see inside the body to diagnose and identify possible medical conditions. An MRI simply samples signals from the water that makes up your body. Specialized antennae create highly defined images that can be used to make diagnoses.

You’ll discover that MRI testing is painless and much quicker than you think. In fact, you’ll probably be very comfortable as you lie on the padded table. The accuracy and speed of the latest MRI scanners means that you will be done quickly and your doctor will have to run fewer – if any - follow-up scans.

Why are MRI scans important?

MRI scans allow doctors to see images of your internal organs and structures in great detail from many angles. This gives them information more quickly, and in many cases more economically, than past tests and exploratory surgeries.

Is an MRI scan like an X-ray?

No. An MRI scan uses a powerful magnet in conjunction with radio frequency waves to generate images of your internal organs and structures. It’s one of the least invasive tests than can see inside the body.

How long will the exam take?

That will depend on what is being studied, but a typical exam lasts between 20 to 60 minutes. You should allow extra time in case the exam takes longer than expected.

Does the machine make a lot of noise?

The magnet makes a slight rapping sound as images are being taken. In between scans the machine is quiet. The MRI technologist will provide you with hearing protection, but its use will not prevent you from hearing the technologist if he or she speaks to you during the exam.

Do I have to hold still the whole time?

It is important for image clarity and the best scan results to hold still during the exam. The technologists will inform you when you many move between scans. Keep in mind a routine scan can take at least 20 minutes.

But keep in mind that an MRI isn’t for everyone. Because of the danger of metal objects within a magnetic field, patients in the following categories should avoid MRI scans:

• Cardiac Pacemaker
• Electromechanical Aids (This includes cochlear implants and spinal stimulators such as a Tens-unit.)
• Aneurysm Clips
• Inferior Vena Cava Umbrellas
• Implanted Drug Infusion Devices
• Metal Workers (Individuals who might have increased risk of intraocular metallic foreign objects.)
• Shrapnel or Bullet Wounds

MRI is not generally recommended for pregnant patients, especially during the first trimester. Certain obstetrical applications are pending FDA clearance.
