These substances are called “contrast products”, capable of absorbing ionizing radiation from the examination and generating images defined on the camera screen. There are different types of contrast with various chemical compositions such as barium sulfate, gadolinium-based contrast, which is based on the examination to be performed, and which can be ingested orally, intravenously or injected into the dry cavity.
