- There are different types of contrast media used in medical imaging123. Here are some examples:
- Oral Contrast Media: containing barium-sulphate, can be administered orally for X-ray, fluoroscopy, and CT images of the gastrointestinal (GI) tract1.
- Intravenous Contrast Media: for intravenous injections across X-ray, fluoroscopic, and CT imaging use an iodine-based substance1.
- Rectal Contrast Media1.
- Microbubble Contrast Media12.
- CT contrast agents: can be mainly divided into ionic and non-ionic, according to the osmotic pressure can be divided into hypertonic, isotonic and hypotonic. Currently, non-ionic, isotonic or hypotonic Contrast Media are used clinically3.
- MR contrast agents: uses gadolinium based contrast agents (GBCA)2.
- Ultrasound contrast agents: can use gas containing micro-bubbles or micro-spheres as contrast agents2.
