An MRI, or magnetic resonance imaging, is a scan that produces detailed images of the inside of the body. MRIs use strong magnetic fields and radio waves to create these images.
What Is an MRI Used For?
MRIs can look at almost any part of the body, including the brain, spine, joints, organs, and more. They’re often used to diagnose tumors, stroke, aneurysms, and spinal problems.
How Does an MRI Work?
The powerful MRI magnet creates a strong magnetic field around the patient. Radio waves are then passed through the body. These waves are absorbed and reflected in different ways by the various tissues in the body. This information is then converted into images by a computer.
How Do I Prepare for an MRI?
There is usually no special preparation needed for an MRI scan. However, if you have any metal implants or devices in your body, you should let your doctor know before the scan. You may not be able to have an MRI if you have certain types of implanted devices, such as a pacemaker.
What Is the Experience Like During an MRI?
During the MRI scan, you will lie on a table that slides into the center of the MRI machine. You will be asked to stay still during the scan. The machine makes loud banging noises during the scan. You will be given earplugs or headphones to help block out the noise. The scan usually takes 30-60 minutes on average.
What Is the Experience Like After an MRI?
After the MRI scan, you can go back to your normal activities. There are no side effects from having an MRI.
Who Interprets Results?
A radiologist will interpret your MRI results and send a report to your doctor. Your doctor will then discuss the results with you and explain what they mean.
When Will I Get Results?
Your MRI results will usually be available within a few days.
What Are the Benefits of an MRI?
MRI scans are very accurate and can provide detailed information about the inside of the body. They’re also non-invasive, which means they don’t involve any surgery or needles.
What Are the Risks of an MRI?
There are no known risks from having an MRI scan. However, if you have any metal implants or devices in your body, you may not be able to have an MRI since these devices can interfere with MRI’s magnetic field and compromise the results. Your doctor can shed more light on this, including the way forward.
