The double contrast method in the examination of the stomach has made possible the radiologic diagnosis of the surface lesions of the mucosa, eg, erosions and early gastric cancer. Changes in the patterns of areae gastricae can be visualized with a good contrast medium. We used a new, more physiologic in vitro method to compare contrast media and study the amounts of adsorption, the degrees of visualization of areae gastricae, and the effects of antifoam solution and blood on media adsorption. EZ-HD surpassed other contrast media on the Scandinavian market in total adsorption on the mucosa and the visualization of areae gastricae. Blood significantly reduces the adsorption of all media, while antifoaming agents have little or no effect.
胃检查中的双重对比法使黏膜表面病变（如糜烂和早期胃癌）的放射学诊断成为可能。使用优质造影剂可观察到胃小区形态的变化。我们采用一种新的、更符合生理的体外方法来比较造影剂，并研究吸附量、胃小区的显影程度以及消泡剂和血液对造影剂吸附的影响。在黏膜上的总吸附量和胃小区的显影方面，EZ-HD超过了斯堪的纳维亚市场上的其他造影剂。血液会显著降低所有造影剂的吸附，而消泡剂的影响很小或没有影响。
