Which statement best describes radiography?

• A. The process of creating radiographic images of internal body structures by passing X-rays or gamma rays through the body
• B. The study of energy production in the human body
• C. The use of ultrasound to visualize soft tissues
• D. The administration of contrast agents for angiography

Answer: (A)

Radiography involves creating images of internal body structures by passing penetrating radiation through the body and recording how those rays are attenuated by different tissues. This attenuation—how much the X-rays are absorbed by bones, organs, and soft tissues—produces a 2D image where dense structures like bone appear brighter and softer tissues appear lighter or darker depending on exposure. This description directly defines the imaging method used to generate radiographs, making it the best match. The other ideas describe different concepts: energy production in the body, ultrasound imaging of soft tissues, and angiography procedures with contrast, which are not how radiography itself is defined.
