How do MRI, PET and CAT scans work?

MRI, PET, and CAT scans are like super special cameras that take pictures of what’s inside your body, no need to cut it open!

MRI stands for Magnetic Resonance Imaging. It uses magnets and radio waves, kind of like a game of hide-and-seek. The magnets make the water in your body spin, and when they stop spinning, they send signals that the machine reads, like a map telling where all the water is inside you.

PET stands for Positron Emission Tomography. It’s like giving your body a tiny flashlight. Doctors put a special kind of sugar into your blood, which lights up in certain spots. The machine takes pictures of these glowing areas to see how well different parts of your body are working, especially the brain or heart.

CAT stands for Computed Axial Tomography, and it’s like taking lots of X-ray photos from all around you and putting them together to make a full picture, just like stacking cookies to see what's inside a jar!

Each scan is a fun, invisible way to peek inside your body without any cuts or stitches.
