Research Abstract |
We prepared pig esophagus for this experiment. Tumors were endoscopically made in the esophagus by injecting a certain amount of hyaluronate sodium. Contrast agents were composed of 2, 5, and 10% of standard barium sulfate solution with thickening agent. After filling the pig esophagus with the agents, CT scans were performed. Transverse and longitudinal images were reviewed. As a result, contrast agents composed of 5 or 10% solution were optimal condition. Oral contrast agent may be possible of clinical use in CT evaluation of esophageal cancers.
