The invention discloses an oral CT (Computed Tomography) contrast agent for gastrointestinal tracts. The oral CT contrast agent comprises the following components in percentage by mass: 0.5-1.5% of edible liquid paraffin, 0.5-1.5% of soybean salad oil, 0.5-1% of sodium carboxymethyl cellulose, 0.1-0.3% of a food additive, 0.1-0.2% of a preservative, 0.5-1% of ioversol or iohexol and the balance of purified water. The gastrointestinal tract contrast performance can be remarkably improved, the contrast agent CT imaging time can be prolonged, the diagnosis efficiency of doctors is effectively improved, the problem that a large amount of water and contrast agents are taken again is reduced, the economic burden of patients is reduced, and the situation that the bodies of the patients are uncomfortable is prevented.
Description
technical field [0001] The invention belongs to the technical field of CT imaging examination, and in particular relates to a CT contrast agent taken orally in the gastrointestinal tract. Background technique [0002] In the X-ray examination of the human abdomen, there are many internal organs and the density of the tissues is roughly similar. It is necessary to introduce a CT contrast agent that is harmless to the human body to improve the contrast of the gastrointestinal tract or lesions in order to achieve ideal diagnosis and inspection results. [0003] Diatrizoate or ioversol, which is commonly used clinically, is mixed with drinking water to assist gastrointestinal CT contrast, because it takes a lot of time for patients to undergo CT examinations and wait for examinations, while diatrizoate or ioversol Ioversol mixed with drinking water is used to assist gastrointestinal contrast in the gastrointestinal tract for a short period of time, and as time goes by, its CT va...
