Medical Imaging History Challenge – Seeing Without Surgery

Medical imaging began in 1895 when Wilhelm Röntgen discovered X-rays. Within weeks, doctors used them to find broken bones and bullets, but early users suffered burns before radiation dangers were understood.

In the 1950s, ultrasound brought safe imaging for pregnancy, and fiber-optic endoscopes let doctors look inside the gut. In the 1970s, CT scanners combined X-rays with computers, and MRI used magnets to image soft tissues.

PET scans showed the body's chemical activity, and today imaging combines techniques with AI to diagnose disease earlier and guide treatments with precision.
