Contrast mediums are used in the medical field for performing diagnostic testing such as magnetic resonance imaging (MRI) scans, computed tomography (CT) scans, and angiography. When these scans are completed, the contrast medium will appear white on the final images, making it easier to observe and evaluate the body parts in question. Contrast injectors are designed to deliver contrast into the proper area of the body safely and without harm to the patient.
Recent advances in medical technology have made these even safer by allowing the administrating physician to use less contrast. This lessens the potential for harm to the patient and also cuts cost by reducing contrast waste. The amount used can now be precisely controlled without having to use a syringe, increasing the chance of excess medical waste as with the more traditional dual syringe injectors the excess medium cannot be used. Lowering the amount of waste produced lowers the cost of the procedure, allowing both medical professionals and their patients to see some savings.
Also, these recent advances can help reduce the amount of leakage into the aorta of extra contrast by up to forty percent. This is a benefit to both the patient and the administrating physician and helps to reduce the risk of complications such as contrast-induced nepropathy. As a constantly evolving field, the emphasis in studying new technology is always placed on patient risk reduction and procedure cost reduction.
As with the older models, syringe free contrast injectors are very safe. However, there are still a few risks. Injury to nerves, arteries, and veins, as well as potential infection, can typically be avoided, but are possible. A somewhat more concerning possible risk is an allergic reaction to the contrast medium. This will occur regardless of what injection system is used. People experiencing allergic reactions often report sneezing or hives. More serious reactions have occurred but are extremely rare. Those with serious kidney problems, particularly those caused by diabetes or requiring dialysis, are often not candidates for diagnostic testing using contrast mediums.
