Part 2: Why are Sounds Generated by the MRI Scanner?
September 13, 2019

As stated in Part 1 of “Why are Sounds Generated by the MRI Scanner,” our Radiology MRI scanners can be described as one big superconducting magnet. Electricity is sent through the copper coils of the machine, which makes the coils vibrate. Depending on the various types of MRI exams, the amount of electricity varies. The vibration of the coils are what makes the various sounds of the MRI machine.

Below are more examples of the various types of MRI exam sounds.


3d ASL, normally used in brain exams
Coronal, normally used in brain or abdomen exams
FIESTA sagital, normally used in brain exams
GRE T1, normally used in brain or abdomen exam
Sag 3D cube FLAIR, normally used in brain exams

Stay tuned for some more examples of our MRI scanner sounds in Part 3.
