X-ray contrast agent for examination of colon and small intestine

摘要

The present invention relates to a novel X-ray contrast agent for inspecting the large intestine and the small intestine, which consists of a water suspension containing 15 to 35 W / V% of barium sulfate and 0.15 to 0.6 W / V% of xanthan gum. When it is in the range of 15 to 20 W / V%, the amount of xanthan gum used is in the range of 0.3 to 0.6 W / V%, and when the concentration of barium sulfate is in the range of 20 to 30 W / V%, When the amount of xanthan gum is in the range of 0.2 to 0.5 W / V% and the concentration of barium sulfate is in the range of 30 to 35 W / V%, the amount of xanthan gum is in the range of 0.15 to 0.4 W / V%. In each case, the higher the concentration of barium sulfate, the lower the amount of xanthan gum used, and the lower the concentration of barium sulfate, the higher the amount of xanthan gum used. X-ray contrast agent for examination of the large intestine and small intestine.;While the X-ray contrast agent has very good fluidity, the X-ray contrast becomes clear to the fine part of the barrier, and the X-ray permeability is remarkably good even in the storage part of the intestine. At least, it brings about a remarkable advantage, such as the fact that skill level is rarely required in the operation of the technician at the time of photography.
