Q: Why are MRI scans important?
A: 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.
Q: Is an MRI scan like an x-ray?
A: No. An MRI scan uses a powerful magnet in conjunction with radio frequency waves to generate images of your internal organs and structures without radiation.
Q: How long will the exam take?
A: That will depend on what is being studied, but a typical exam lasts between 20 and 60 minutes. You should allow extra time in case the exam lasts longer than expected.
Q: Does the machine make a lot of noise?
A: The magnet makes a slight rapping sound as images are being taken. In between scans the machine is quiet. Headphones are available to you, but their use will not prevent you from hearing the technologist if he or she speaks to you during the exam.
Q: Do I have to hold still the whole time?
A: It is important for image clarity and the best scan results to hold still during the exam. The technologists will instruct you as to when you may move between scans. Keep in mind that a routine exam may take at least 20 minutes.
Q: Will I be alone?
A: You will be in contact with a technologist at all times. Even when he or she is not in the MRI room, you will be able to talk to him or her by intercom. In some cases, a family member is welcome to stay in the room with you during your scan.
What exactly is MRI?
MRI stands for Magnetic Resonance Imaging, which is a powerful, dynamic way for doctor's to see inside our bodies to diagnose and identify certain problems and diseases.
An MRI is not an X-ray but a combination of magnetic fields, radio waves, and a computer that all work together to create two or even three-dimensional images of exactly what's happening within us.
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 back on the padded table. You may even be able to listen to your favorite music as you're scanned.
Many of your questions about MRI's are answered here. Should you have any other questions or concerns, please feel free to consult your caregiver. | |
Magnetic Resonance Imaging is one of the most useful tools physicians have to make an accurate diagnosis and select an appropriate treatment for their patients. Because these images are computer generated, they can be instantly sent electronically to off-site specialists and consultants. Thanks to advanced design features, your MRI should prove perfectly comfortable. In fact, you may even find the experience relaxing.
But keep in mind that an MRI isn't for everyone. So be sure to inform your physician if you have a pacemaker, aneurysm clips in the brain, a shunt with telesensor, inner ear implants, metal fragments in one or both eyes, implanted spinal cord stimulators, or if you're pregnant, breast feeding, or have anemia or any disease affecting red blood cells. |
