Why does an MRI make different noises? This video takes a rare look inside MRI scanners to show you what actually makes the different sounds during MRI scans. The sounds in MRI are produced by only 3 components in the MRI scan room: The coldhead, RF coil and gradient coil. Topics include chirping sound in MRI, what makes MRI scans so loud, why does an MRI make a loud knocking noise and more. Join us as we demystify MRI scan sounds. Thank you for watching! Revision note: In this video, we used the term "sublimation" around timestamp 0:50 to describe the process of boil-off of liquid helium in MRI machines. However, it's important to clarify that a more accurate term for this phenomenon would be "expansion." Liquid helium doesn't undergo sublimation when transitioning to its gaseous state in this context. This correction ensures a more precise understanding of the process.
