Medical Imaging Trivia Quiz – Seeing Inside the Body

Before 1895, doctors could only look inside the body through surgery. Wilhelm Röntgen's discovery of X-rays changed medicine almost overnight, letting doctors see bones and find bullets and fractures without cutting.

Later inventions showed soft tissues and body functions. Ultrasound used sound waves, CT scanners combined many X-ray images with computers and MRI used magnets and radio waves. PET scans revealed how organs work by tracking radioactive tracers.

Medical imaging has saved countless lives by detecting disease early. Today artificial intelligence is helping doctors read scans faster and more accurately.
