What is the noise in MRI?
During an MRI exam the MR machine produces a number of noises that can be fairly loud. These noises come from the actions of the machine itself as it generates the information that is used to produce the images. During the exam, a part of the machine called the "gradient coil" vibrates very rapidly, as it turns a small magnetic field on and off many times per second. This gradient coil adds a small layer of magnetism on top of the stronger magnetic field that is on permanently inside the scanner. The additional layer of magnetism is called a gradient (like the slope of a road when it is on a hill or grade) because the local strength of the magnetic field can be adjusted so that it becomes stronger going from left to right, from front to back, or from head to toe. These local variations in the strength of the magnetic field are used by the computer to help determine the location of the radio signals that are produced inside the body, so they can be properly represented on an image of the patient.
As the gradient coil turns on and off rapidly, the interactions of the weak gradient magnetic field with the stronger main magnet create sound waves in the same way as does the magnet in a loudspeaker. The pattern and loudness of these noises varies throughout the exam depending on the type of scan sequence that is being performed.
Fortunately, the sounds of the magnet can be hidden by wearing ear phones, and can be covered up by listening to music through the ear phones. Patients may listen to a favorite CD or to any of a number of satellite radio stations during the exam, so the auditory experience inside the MRI machine may actually be a pleasure.
Here's one of my favorite little poems in honor of Breast Cancer Awareness Month.
A Friend is Like a Good Bra......
Hard to find,
Always lifts you up,
Never lets you down or leaves you hanging,
And is always close to your heart!
