What makes mri so noisy

An MRI has four magnets inside it- a large principle magnet and three smaller magnets. The smaller magnets gradients are inside a large metal coil called a gradient coil. As electrical current is applied to the MRI to create an image, the coil expands and contracts rapidly you could even think of it as vibrating causing the loud noise you hear as you pass through the bore.

It was quite large and, truth be told, it seemed to have a lot of empty space. So why are they so huge? The answer came in two parts:. Constant cooling- In order to keep a magnet stable, it must be kept cool constantly. MRI technologists use different pulse sequences and orientations to capture the angle, contrast and area they need. Patients use different words to describe the sounds they hear, including:. At Envision Imaging, our technologists provide headphones that play music during your scan.

Some MRI machines have a design meant to reduce the noise it makes during scans. Currently, this technology tends to compromise image quality in exchange for less noise. As MRI technology develops, researchers hope to create a quieter machine with clear images.
