MRI, or magnetic resonance imaging, is a way to take detailed pictures of the body using powerful magnets. Unlike other forms of imaging (such as X-ray, CT, and fluoroscopy), there is no ionizing radiation emitted from the MRI machine.
In order to create the magnetic field to take your pictures, we need to use a ton of electricity. Because an MRI machine requires so much energy, it saves on overall power usage by leaving the magnet running all the time, rather than constantly turning it on and off everyday. Therefore the magnet is always on!
The electricity flows through miles and miles of tightly wound wires (or coils) inside the MRI machine. When the electricity runs through the machine, this causes the wires to begin to vibrate, giving off those loud banging and buzzing noises that your child will hear while being scanned. The electricity moving through those wires gives off a magnetic field. The MRI technologists are able to manipulate the different frequencies emitted by the magnetic field to match frequencies in our bodies. Since hydrogen molecules are present in almost every organ of the body, we match the frequency of our machine with the frequency of our hydrogen molecules. The two frequencies now resonate together, hence the name magnetic resonance imaging. When the frequencies of your child’s body and the magnetic field are in sync, we are able to collect data and form that data into pictures of your child’s internal organs.
