A new oral contrast agent for CT of the esophagus was evaluated for its ability to coat the esophageal lumen in 12 patients with esophageal diseases. This agent is made of carboxymethyl cellulose sodium, potato starch and low-density barium, and has remarkably high viscosity of 13600 centipoise. 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 78.7, 86.4, and 63.4%, respectively, for all patients. This agent is expected to play a possible role in the CT diagnosis of esophageal cancer by helping to determine the indications for radical surgery and/or radiotherapy.
一种用于食管CT的新型口服造影剂在12例食管疾病患者中进行了食管腔涂布能力的评估。该造影剂由羧甲基纤维素钠、马铃薯淀粉和低密度钡制成，具有高达13600厘泊的显著高粘度。将食管分为近端、中段和远端节段，以分析管腔显影的有效性。所有患者这些节段的平均显影百分比分别为78.7%、86.4%和63.4%。该造影剂有望通过帮助确定根治性手术和/或放疗的适应症，在食管癌的CT诊断中发挥可能的作用。
