Medical imaging is a type of diagnostic procedure that allows doctors to view the inside of the body in a non-invasive manner. Medical imaging includes x-ray radiography, ultrasound, magnetic resonance imaging (MRI), computerized tomography (CT) scans, and positron emission tomography (PET) scans. Contrast is a substance that is ingested or introduced into the veins with contrast Injectors just before a medical imaging exam. The contrast fluid highlights certain internal structures to make them easier to examine. Contrast is often used for imaging of the blood vessels or the intestinal tract. There are several different types of contrast fluids, and they are used for different purposes.
For X-rays, the most common contrasts are iodine and barium. Both of these keep light from passing through, making them show up distinctly in an x-ray image. Gadolinium is used for magnetic resonance imaging (MRI). This chemical changes the magnetic property of water in the body in a way that produces a clearer image. Ultrasound imaging does not always involve a contrast, but a saline or air microbubble contrast is used to check for a cardiac shunt, an irregular pattern of blood flow in the cardiac system, during an ultrasound exam. While barium contrast is either ingested or administered rectally, iodine and gadolinium are injected into the veins.
Contrast injectors can be manual or automated. While manual injectors are still commonly used and preferred by the medical personnel who give the injection, hospitals and radiology clinics appreciate the efficiency and data management capability of automated systems. Two types of automated injectors are syringeless injectors and double-headed injectors. The syringeless injector injects the fluid through hydraulic pressure. It is an efficient process, and the device is fairly easy to use. A double-headed injector uses one head to open the vein with a saline injection and another to inject the contrast. This method reduces the risk of infection after an injection.
If you are looking to purchase Contrast Injectors, you may be able to find high-quality used equipment that will be less expensive than the original equipment manufacture (OEM) price. Look for a company that maintains the products it sells. For more information about contrast injectors, Visit Precise Bio Medical.
