Susceptibility weighted imaging

Susceptibility weighted imaging (SWI) is a way for doctors and scientists to take pictures of your brain to see what is happening inside.

Your brain is made up of lots of tiny cells and structures that help it work properly. Sometimes, doctors need to look very closely at these structures to see if there is anything out of the ordinary. That's where SWI comes in!

When scientists use SWI, they are looking specifically at how different parts of your brain respond to magnetism. Your brain is magnetic because it has a lot of iron inside it. When the magnetic field of the machine is aimed at your brain, it causes the iron inside your brain to react in a certain way.

By looking at how the iron inside your brain is reacting, doctors can get a very clear picture of what is happening inside. This can help them see if there is anything that they need to be worried about, like a growth or a problem with blood vessels.

SWI can be very helpful in diagnosing certain conditions, and it can even help doctors plan surgeries to treat brain illnesses. Plus, since it doesn't require any radiation or harmful substances, it is completely safe for kids and grown-ups alike!
