直——乙状结肠是大肠造影检查中提示问题较多的部位。原因是此段肠曲深居盆腔、形态不规、迂曲重合,触摸受限,缺少标准投影体位之故。为了提高此区的X线诊断效能,我们在例行的造影检查的基础上,侧重观察了双重造影于此区的应用和摄影方法。就此介绍。造影方法清肠法,在Brown氏清肠法的基础上,采用番泻叶做为主体清肠剂,进行彻底清肠。钡剂调配质量要求浓度高、稠度低、颗粒细、粘附性好、不起泡,和用于胃造影时的钡剂要求一致。其造影过程:
The straight-sigmoid colon is a part of the large intestine angiography. The reason is that this segment of the bowel is deep in the pelvic cavity, irregular in shape, distorted by coincidence, limited touch, and lack of standard projection position. In order to improve the X-ray diagnostic efficiency in this area, we focused on observing the application and photographic methods of double contrast in this area on the basis of routine angiography. Introduce this. Contrast-enhanced bowel method, based on the Brown’s bowel method, using senna leaf as the main bowel cleansing agent. The preparation quality of the elixir requires high concentration, low consistency, fine particles, good adhesion, no foaming, and is consistent with the elixir requirement for use in gastric angiography. The imaging process:
