摘　　要：目的：探讨胃肠道准备对腹部PET／CT影像诊断的影响。方法：回顾性分析476例腹部做PET／CT检查的患者，383例在PET／CI检查前应用654-210mg肌肉注射及饮水500-1000ml，对照组93例未进行胃肠道准备。对两组所得图像进行比较。结果：在383例行胃肠道准备的患者中，有13例出现胃肠道干扰影像，占3．4％（13／383）；而93例未进行胃肠道准备的有18例出现胃肠道干扰影像，占19．4％（18／93），两组比较差异有统计学意义（X^2=31.31，P＜0.05）。结论：胃肠道准备可明显提高腹部PET-CT检查的图像质量。Objective：To study the influence of gastre-intestinal preparation （GIP） on imagic quality for PET-CT. Methods：476 eases of abdominal PET/CT were analysed. 383 cases of abdominal PET/CT were prepared the gastrointestine before examination, 93 eases as control groups were not prepared and compared the image quality in two groups. Results： 13 cases of gastrointestinal image were intervened in 383 eases with gastro-intestinal preparation. 18 eases of image were intervened in 93 cases without gastreintestional preparation. There is significance difference between preparation and non-preparation before PET/CT examination. Conclusion： It is important to prepare the gastrointestine before abdominal PET/CT examination and reduce the interfere factors of image quality.
