barium-meal

This term refers to a specific diagnostic procedure rather than a nutritional meal. It is used primarily in clinical settings to describe the process of using a radiopaque contrast agent to visualize the upper gastrointestinal system. Because it is a technical medical term, it is rarely used in casual conversation unless a patient is describing their medical history.

In a clinical context, the term is often used interchangeably with "barium swallow" or "upper GI series," though "barium-meal" specifically emphasizes the ingestion of the contrast medium to examine the stomach and duodenum.
