消化系统所属的各器宫在X射线萤光板上和摄影胶片上所呈现的阴影浓度大致相似,很难明确鉴别,这样就不能得到正确的诊断,因此必须使用造影剂,使其被检查部位的密度增加,而便於分辨。常用的消化道造影剂,是硫酸钡,此药为一种白色粉末,不溶於水,也不会因酸碱性变化而变为其他可溶的物质,故在X射线造影时,不易被胃肠所吸收。但有些不纯粹的钡,其中含有各种钡化合物,如不注意而服用,则往往引起钡中毒,严重的可致死亡。所以当给患者服钡时,应特别注意,对新用的或没有说明单的,必须进行分析和检查,如果上面注明有[X射线专用]或[X射线造影用],才
The digestive system belongs to the palace on the X-ray fluorescence plate and photographic film presented by the shadow concentration is similar, it is difficult to clearly identify, so you can not get a correct diagnosis, it is necessary to use contrast medium, so that the site being examined Increased density, easy to distinguish. Commonly used gastrointestinal contrast agent is barium sulfate, the drug is a white powder, insoluble in water, will not change due to acid-base and other soluble substances, so in X-ray contrast, not easy to stomach Absorption of intestine. However, some not pure barium, which contains a variety of barium compounds, if taken without notice, it is often caused by barium poisoning, severe can cause death. Therefore, when serving barium to patients, special attention should be paid, with or without a single new, must be analyzed and examined, if the above indicates that there is [X-ray special] or [X-ray contrast] only
