What is the common name for a radiograph?

A radiograph is commonly known as an X-ray. This imaging technique uses a form of electromagnetic radiation to create images of the interior structures of the body, particularly useful for examining bones and detecting various medical conditions. The term "X-ray" specifically refers to the process of using radiation to obtain images, while "radiograph" is the resulting image produced from that process.

CT scans, magnetic resonance images, and ultrasounds are different imaging modalities that utilize various principles and technologies. CT scans, for example, involve the use of X-rays taken from multiple angles to produce cross-sectional images. Magnetic resonance imaging (MRI) employs strong magnetic fields and radio waves to create detailed images of organs and tissues. Ultrasound uses sound waves to visualize soft tissues in real-time. Each of these techniques has its own unique applications and purposes in medical diagnostics, but they are not synonymous with the term radiograph.
