胃肠道低张双对比造影现已广泛应用于临床,能发现普通口服法、灌肠法所不能发现的病变。我们在参考其他作者方法基础上做了些改进,现将62例结肠双对比造影检查体会总结如下: 一、机器选择与钡剂调配:用XG——200型X线诊断机,X线管为固定阳极。 采用上海马陆化工厂和西安长城制药厂两种钡粉,具有高浓度、低粘度、颗粒粗细适宜的特点,经调配后流动和涂抹性能明显优于其它钡份。硫酸钡颗粒的粗细直接影响悬浮和附着。 调配浓度为75％W/V。曾用60～65％和80％以上浓度试验,前者浅淡附着差;后者粘度高,流动性差,且不易涂布。两者都影响诊断和观察。为了消除在注入造影剂或/和气体时所产生的气泡,有
Gastrointestinal hypotension double contrast angiography has been widely used in clinical, can find common oral method, enema can not be found lesions. We made some improvements on the basis of reference to other authors’ methods. Now 62 cases of colon double contrast imaging experience are summarized as follows: First, machine selection and barium deployment: XG - 200 X - ray diagnostic machine, X - ray tube Fixed anode. Using two kinds of barium powder from Shanghai Malu Chemical Factory and Xi’an Great Wall Pharmaceutical Factory, it has the characteristics of high concentration, low viscosity and suitable particle thickness. After being mixed, the flowability and smear performance are obviously better than other barium parts. The thickness of barium sulfate particles directly affect the suspension and adhesion. Dispensing concentration of 75% W / V. Had used 60 ~ 65% and 80% concentration test, the former shallow poor adhesion; the latter high viscosity, poor mobility, and difficult to coat. Both affect diagnosis and observation. In order to eliminate bubbles in the injection of contrast medium or / and gas, there
