Background
Contrast is a medical term used in radiodiagnostics by taking a substance containing elements with high atomic number and then taking radiographs of a pre-diagnosed in vivo site for medical diagnosis. Radiography is a commonly used X-ray examination method. Despite the existence of Computed Tomography (CT) which has 100 times greater resolution of tissues and organs than normal X-rays, radiography remains an important auxiliary examination method.
Contrast agents are required in the contrast process, and include positive contrast agents and negative contrast agents, and the common positive contrast agents include the following classes:
firstly, the contrast agent is excreted by kidney and is mainly used for imaging urinary system and cardiovascular;
② contrast agent excreted by liver and gallbladder, such as abscisic acid;
③ the contrast agent is oil and fat contrast agents, such as iodized oil, iodophenyl ester and the like, and is mainly used for the contrast of pipelines such as bronchus, uterus and the like and body cavities and the like;
fourthly, the solid contrast agent, such as barium sulfate, is prepared into suspension to be swallowed or clystered for gastrointestinal radiography.
When contrast injection is performed on an oil contrast medium, a large amount of air bubbles are generated in the oil storage barrel due to factors such as air pressure, and if the air bubbles are not eliminated, the contrast injection is affected.
