Q: How does the MRI machine work?
A:
The machine measures the radio waves sent through your body by a strong magnetic field in order to create a picture of the inside of your body.
Q: Why do I have to have an MRI?
A: An MRI is the fastest, most accurate way for your doctor to detect abnormalities, including their location and what tissues are involved.
Q: How can I prepare?
A: Most of the time, there is no need to restrict your diet or regular routine. You can take regularly scheduled medications unless there are specific instructions. If there is any need for further preparation, instructions will be given to you at the time of making your appointment.
Q: Are there any restrictions for an MRI?
A: Yes, and your physician will go over all of these before making your appointment. Because the MRI machine uses a strong magnetic field, which will move objects made with iron or steel, let your doctor know if you have:
-
A pacemaker
-
Aneurysm clips
-
Cochlear implants
-
A neurostimulator (TENS unit)
-
Metal implants
-
Steel surgical staples or clips
-
An implanted drug infusion device
-
Any implant made partially or wholly of iron or steel
-
If you're pregnant, let the doctor know.
