Why does the MRI Machine make so much noise?

This is probably one of our most frequently asked questions in MRI. The MRI machine uses a combination of a strong magnet, radio transmitter and receiver. When the sequences are performed, electric current is sent through a coiled wire-an electromagnet. The switching of the currents causes the coils to expand making loud clicking sounds. The sounds vary depending on the type of sequences being used and some are louder than others. While the noise is produced by turning on and off the currents the MOST important factor to remember is that the MAGNET IS ALWAYS ON. The main magnet is always on and this is why everyone entering the scan room must be safely screened to ensure their safety. All equipment used in the MRI environment is special (nonferrous) for MRI.
