The practice of clinical diagnostic radiology has been made possible by advances not only in diagnostic equipment and investigative techniques, but also in the contrast media that permit visualisation of the details of the internal structure or organs that would not otherwise be demonstrable.There are numerous types of contrast media which have different applications, depending on their differing chemical and physical properties. Radiological contrast media are usually water soluble solutions, but there is one commonly used variety that is based on a suspension of large insoluble particles. This is the barium sulphate mixture that is used for barium meal and barium enema examinations of the upper and lower gastrointestinal tracts. Barium sulphate suspensions have better coating properties than the iodinated contrast media, and tend to form thin layers spread over the lining of the gut.surMe

Adjustment of the mirror will change the contrast slightly.
Growth media containing carbon sources,nitrogen sources and trace elements is used. Nitrogen media including organic and inorganic is also used for Industrial fermentation.
LOM can be used as x-ray contrast media in patients allergic to iodine.

Patients with kidney disease or injury may suffer further kidney damage from the contrast media used for angiography. Patients who have blood-clotting problems, have a known allergy to contrast media, or are allergic to iodine may also not be suitable

In imaging studies, contrast media is used to enhance visualization of anatomical structures. Double contrast involves using both positive and negative contrast agents to highlight different tissues or structures in the body, such as in barium enemas. Single contrast only uses one type of contrast agent, typically a positive agent, to highlight specific structures of interest, like in a barium swallow. Double contrast provides more detailed information but requires more time and expertise to interpret, while single contrast is simpler and quicker but may offer less detail.
