The result of the experiment showed that the qualitative medium - speed filter paper can be used as the material of the nitrite - detecting paper: color developing reagent A containing 4 - aminobenzene sulfonamide and N - 1 naphthyl ethylenediamine hydrochloride, and mixtures of 1 : 1 naphthylamine solution and sulfanilic acid solution as color developing reagent.

实验结果表明：定性中速滤纸可以作为亚硝酸根试纸的材料；含有4-氨基苯磺酰胺和N-1-萘基乙二胺盐酸盐的显色剂A及含有1：1的α-萘胺溶液和对氨基苯磺酸溶液的显色剂B，按1：1混合后可以作为显色剂；通过应用实验表明，亚硝酸根试纸具有体积小、便于携带、检测方便、成本低廉等特点。

SBFT is considered a reliable approach to imaging the small bowel in inflammatory bowel disease, provided that it is a dedicated study, incorporating fluoroscopy with manual manipulation.4 The sensitivity and specificity of SBFT in terminal ileal disease is reported in the range of 85–95% and 89–94%, respectively, but these parameters are highly dependent on the experience of the radiologist.5 6 Although some radiologists favour SBE7 8 using a nasally placed enteric tube, SBFT can be at least as sensitive as SBE and is preferred by patients as no nasal intubation is necessary.9

欧洲相比北美更加倾向于使用腹部超声作为CD腹部影像学检查的标准途径。关于超声将在后面总结。IBD的早期诊断和和病情活动度的重新评估比较具有挑战性。确诊IBD的患者往往需要终身进行反复的检查。为了便于患者的诊断、随访和治疗，不断有新的影像学方法出现。本文将着重讨论这些进展。表1对比了小肠CD的各种影像学检查，以及最容易引起争议的地方。
