Introduction of contrast media through the tongue, which may result in tongue irritation, vomiting, tongue swelling, and salivation.
A Double Contrast Study uses two kinds of contrast media to enhance imaging of the anatomical structures.
Substances having high or low atomic numbers compared to adjacent structures, administered to the body to fill hollow organs and make them visible to the film, used to differentiate densities inside the body.
Introduction of contrast media through the eyes, which may lead to redness of eyes, eye irritation, and eye swelling.
Reactions can be classified as mild (no treatment necessary, observation important), moderate (requires some treatment but no hospitalization), and severe (requires hospitalization and can be life-threatening).
A Scout Film, also known as a survey, preliminary, or initial film, is a radiograph taken before the administration of contrast media to check patient preparation, organ positioning, and identify foreign bodies.
Solution (oil or water-soluble), Tablet, Granules or powder.
Air and Gases, Heavy Metallic Salts (like Barium Sulfate), Inorganic Iodides, Organic Iodides, and Iodized Oils.
Introduction of contrast media through the veins, which may result in itchiness, nausea, vomiting, and dizziness.
Epinephrine acts as a bronchodilator and is used for treating severe allergic reactions.
The types of radiographic contrast studies include Single Contrast Study, Double Contrast Study, Dual Contrast Study, Mucosal Phase Study, and Filling Phase Study.

Verify the right patient, right contrast media, right amount, avoid bare-hand contact, and record on the patient chart.
A process of introducing 1 cc or 1 ml of pure contrast media to the patient to check if there is any reaction or adverse effect to the patient.
The qualities of Barium Sulfate include its high atomic number, relative cost-effectiveness, low irritation, and non-absorbable nature.
Substances that partially absorb x-ray, appearing black on the radiograph.
Barium Sulfate is a positive contrast media with a high atomic number that renders a white image on the film, is non-absorbable, and can cause constipation if retained in the colon for a long time.
The types of Barium Sulfate mixtures include: Paste Mixture (3/4 BaSO4 and 1/4 water), Thick Mixture (1/2 BaSO4 and 1/2 water), Thin Mixture (1/4 BaSO4 and 3/4 water), and Milk Mixture (2 Tbsp. BaSO4 with a glass of water).
Substances that absorb x-ray, appearing white on the radiograph, and have a high atomic number, including Barium Sulfate and water-soluble iodine.
Oral, Parenteral (Intravenous, Intrathecal, Intra-arterial), Intubations (T-tubes, NG Tube), and Rectal administration.
Introduction of contrast media through the skin, which may cause dilatation, vomiting, and salivation.
It must clearly show structure, be physiologically inert, produce minimal toxicity, and be eliminated unchanged.
Ampoule Benadryl (Diphenhydramine HC), which is generally administered intramuscularly.
Disadvantages of using Barium Sulfate include its colloidal suspension (cannot be dissolved in water) and contraindications in cases where perforation is suspected or if surgery is likely to follow.
