What type of contrast is likely used for an esophagus study looking for a perforation?

Barium sulfate
Gadolinium
Iodinated contrast
Air contrast

The correct answer is: Iodinated contrast

When conducting an esophagus study to evaluate for a perforation, iodinated contrast is the preferred choice due to its water-soluble properties. In the event of a perforation, barium sulfate can pose a significant risk because it is not water-soluble and can lead to complications if it leaks into the mediastinum or peritoneal cavity. Iodinated contrast, on the other hand, is water-soluble and can be absorbed by the body, thereby minimizing the risk of irritation or inflammation in the event of a perforation. Iodinated contrast agents are effective at providing clear imaging during fluoroscopy or CT examinations while allowing for a safer option in case there is a disruption in the integrity of the esophagus. This property makes them the most suitable choice for evaluating potential perforations compared to other types of contrast agents, which may not provide the same level of safety in such situations.
