Why does an MRI make noise?
An MRI scan can be scary because of the loud noises made by the machine. But fear can be relieved if you know a little more precisely how the device works.
How an MRI works and where the noise comes from
The abbreviation MRI stands for magnetic resonance imaging. If you look at the full name, you already know why the short form is always used. Since the procedure is based on the principle of magnetic resonance, it is also often used in popular parlance by magnetic resonance imaging or magnetic resonance imaging. Called nuclear spin.
- With this method it is possible, similar to X-rays, to depict the inside of the human body. The big difference, however, is that no X-rays or the like are used here. The sectional images of the body are generated with the help of magnetic fields.
- The atomic nuclei in body tissue have a magnetic charge or the ability to build up such a charge. Static and high-frequency magnetic fields are used to try to make the nuclei move in a certain way. This movement is then visible in the form of an alternating voltage, which can ultimately result in an image. When the magnetic fields build up, the sometimes frightening noises arise.
When to use MRI treatment
An MRI works with magnetic fields and these are also the reason for the loud noises. But when do you have to expect such treatment?
- An MRI scan is actually always carried out when doctors want to take a closer look at individual organs, joints or parts of the body. With the images obtained in this way, the medical professionals are able to see a problem directly instead of blood tests etc. only to guess.
The MRI, the magnetic resonance tomograph, is an excellent way to diagnose ...
- There are now several MRI procedures that are different for each other Investigations be applied. Real-time MRI, for example, can produce cinematic representations of joints or organs. Functional magnetic resonance imaging is used to examine the brain. Tissue blood flow is examined using a perfusion MRI and vessels are visualized using magnetic resonance angiography.
So if you are due for such an examination or a similar one, do not worry. The noises are harmless and only serve to generate magnetic fields. In addition, the staff is very well trained and gives you detailed instructions on what to watch out for.
