A Barium Swallow can visualize the upper G.I. tract. The person is given a cup of special barium solution mixed in juice to make it palatable--not taste so bad. The person is told when to sip as X-rays are taken. The series starts with the person standing up, then laying flat.
Oil-based iodinated contrast media are used primarily in radiography for procedures where prolonged visualization of the gastrointestinal tract is needed, such as barium enema. These contrast agents are denser and are not water-soluble, allowing better coating and adherence to the mucosal surface for improved visualization. They are typically used in cases where water-based contrast media are inadequate.
You can label contrast media by writing the patient's name and identification number on the label provided with the contrast media or by affixing a pre-printed sticker with the necessary information onto the contrast media container.
Water-soluble iodinated contrast media is typically used for hysterosalpinography. This type of contrast media allows for clear visualization of the uterine cavity and fallopian tubes during the procedure.
LOM can be used as x-ray contrast media in patients allergic to iodine.

Barium sulfate is used in X-ray imaging of the gastrointestinal system because it is radio-opaque, meaning it shows up clearly on X-ray images. When a patient ingests a barium sulfate suspension, it coats the inside of the digestive tract, allowing the radiologist to visualize the structures of the stomach and intestines more clearly during imaging procedures.

Contrast media contain substances that attenuate X-rays and help highlight specific structures in the body. When injected or ingested, contrast media enhance the visibility of blood vessels, organs, or tissues on imaging studies such as CT scans or MRI scans. This improved contrast allows healthcare providers to obtain a clearer image for diagnostic purposes.
