Global radiology is a medical field where special doctors called radiologists look at pictures of people's insides, such as their bones, organs, and tissues. They use special machines like X-rays, CAT scans, and MRI machines to take these pictures.
Now, imagine you are in a big classroom with other children, and the teacher has a big map of the world. Global radiology means using these special machines and doctors to help people all around the world, no matter where they live.
Some places may not have as many of these machines or trained doctors, so global radiologists work to help those places out. They also use technology to share pictures and findings with other doctors around the world to give the best possible care to their patients.
In short, global radiology is like having a map but instead of teaching geography, doctors are working together to help people all around the world see their insides and stay healthy.
