Name one common diagnostic imaging technique used in radiology.

X-ray is a fundamental and widely utilized diagnostic imaging technique in radiology. It works by passing a controlled amount of ionizing radiation through the body, where it is absorbed to varying degrees by different tissues. This differential absorption creates an image on a film or digital detector, which allows radiologists to visualize the internal structures of the body, such as bones and certain organs, to diagnose various conditions, assess injuries, and monitor ongoing treatment.

As one of the oldest forms of medical imaging, X-rays are commonly used due to their speed, accessibility, and effectiveness in providing critical information in a wide range of clinical situations. They are particularly useful for identifying fractures, dental issues, and lung conditions, among other applications. X-ray technology continues to evolve, but its core principles remain essential to the practice of radiology today.
