Which discovery enabled physicians to diagnose diseases by viewing internal anatomy without invasive procedures?

• A. Endoscopy
• B. Ultrasound
• C. X-ray imaging
• D. MRI

Answer: (C)

Viewing internal anatomy without surgery relies on imaging that turns what’s inside into pictures. The breakthrough was the discovery of X-ray imaging by Wilhelm Röntgen in 1895. Radiographs let doctors see bones and other structures through the body without making an incision, enabling rapid diagnosis of injuries and diseases. This noninvasive view established radiology as a key diagnostic field and opened the door to countless uses in medicine. Other options involve either inserting instruments into the body (endoscopy) or rely on different physical principles (ultrasound using sound waves, MRI using magnetic fields) and were developed after X-rays, so they didn’t represent the foundational discovery that first made internal noninvasive viewing possible.
