【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/CT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(χ2=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。更多还原

【Abstract】 Objective:To study the influence of gastro-intestinal preparation (GIP) on imagic quality for PET-CT.Methods:476 cases of abdominal PET/CT were analysed. 383 cases of abdominal PET/CT were prepared the gastrointestine before examination, 93 cases as control groups were not prepared and compared the image quality in two groups.Results:13 cases of gastrointestinal image were intervened in 383 cases with gastro-intestinal preparation. 18 cases of image were intervened in 93 cases without gastrointestional 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.更多还原
