螺旋CT增强技术适于对小肠的评价,以获得更好的肠系膜血管影像。这有助于小肠病变的早期诊断及其活动性的评价。水作为中性口服对比剂可避免阳性对比剂,如稀释的钡剂、碘溶液对细微的粘膜异常或肠壁强化的细小变化的影响以及对CTA 3D后处理的干扰。 作者为确定小肠的正常强化,以水作为口服对比剂并采用经静脉增强双期螺旋CT技术对50例健康的潜在供肾者进行研究。所有对象均于检查前
Spiral CT enhancement technique is suitable for the evaluation of the small intestine to obtain better mesenteric vascular images. This contributes to the early diagnosis of small bowel disease and evaluation of its activity. Water as a neutral oral contrast agent avoids the effects of positive contrast agents such as dilute barium, iodine solutions on subtle mucosal abnormalities or small changes in bowel wall enhancement as well as interference with CTA 3D post-treatment. In order to determine the normal enhancement of the small intestine, 50 healthy potential donors were studied using water as an oral contrast agent and intravenous double-phase enhanced spiral CT. All subjects are examined before
