The buffer capacities of the BaSO4, contrast media are poor. Yet the pH changes caused by effervescent agents or gastric contents are insignificant for mucosal adsorption. The increase of the viscosity and decrease of the density impair the results of the examination.
硫酸钡造影剂的缓冲能力较差。然而，泡腾剂或胃内容物引起的pH值变化对黏膜吸附而言微不足道。粘度的增加和密度的降低会影响检查结果。
