Contrasted radiology uses ionic radiation to treat malignant cancer cells. It is a contrast medium that helps in improving the visibility of structures using X-ray based imaging, radiography and fluoroscopy. These agents are generally iodine or barium compounds. Magnetic resonance imaging or MRI as it is known, functions similarly though with different principles and thus utilizes different contrast agents. These compounds work by altering the magnetic properties of nearby nuclei. Iodine based contrast radiology are of two type, ionic and non-ionic. Iodine contrast agents are used for angiography, venography etc. Ionic contrast agents have more side effects whereas non-ionic agents have fewer side effects. Barium sulphate is an agent that is used in the imaging of the digestive system. It is an insoluble white powder that is used to increase the contrast in the GI tract. It is an opaque white mixture and is usually swallowed or administered as enema. It is used only for the digestive tract and it leaves the system along with the faeces. Modern contrast agents are well tolerated by the body. The side effects of radio contrast are contrast- induced nephropathy. Contrasted radiology is effective but there is discomfort while using various contrast radiology tests. However, it is usually minor. The treatment is done is short sessions for a few days depending on the diagnosis and the severity of the problem.
