X-RAY CONTRAST MEDIUM FOR EXAMINING LARGE AND SMALL INTESTINES. |
摘要 |
An X-ray contrast medium for examining large and small intestines comprises an aqueous suspension containing 15-35 % (by W/V, the same applies hereinbelow) of barium sulfate and 0.6-0.15 % of xanthan gum, wherein the amount of the gum is reduced as the concentration of the sulfate is increased and vice versa, more specifically, the amount of the gum is 0.3-0.6, 0.2-0.5 and 0.15-0.4 % when the concentration of the sulfate is 15-20, 20-30 and 30-35 %, respectively. This medium has an extremely good fluidity, gives a clear contrast even in a minute portion of an intestinal wall, and improves the transmittance of X-rays. Therefore, it has remarkable merits such that the frequency of the postural change of a subject can be reduced and the requirement for the expertism of the operator can be reduced. |
