A new 3% barium paste for use in CT of the esophagus was evaluated for its ability to coat the esophageal lumen in 31 patients. The esophagus was divided into proximal, mid, and distal segments to analyze the effectiveness of lumenal opacification. The average percent opacification of these segments was 74.5, 87.7, and 60.8%, respectively, for all patients. These results indicate that this product visibly coats the esophageal lumen in the majority of patients. We found that it is easy to use, is well tolerated, and did not produce scanning artifacts. We conclude that this new oral contrast agent could be used routinely in CT of the esophagus or in selected cases to clarify problem areas.
对一种用于食管CT检查的新型3%钡糊剂进行了评估，观察其在31例患者中覆盖食管腔的能力。将食管分为近端、中段和远端节段，以分析管腔显影的效果。所有患者这些节段的平均显影百分比分别为74.5%、87.7%和60.8%。这些结果表明，该产品在大多数患者中能明显覆盖食管腔。我们发现它使用方便，耐受性良好，且未产生扫描伪影。我们得出结论，这种新型口服造影剂可常规用于食管CT检查或在某些特定病例中用于明确问题区域。
