In the last years there are a lot of developments in endoscopical, radiological and sonographical imaging techniques for example virtual colonoscopy, capsule endoscopy and contrast-enhanced sonography. The MR- or CT-colonography has a high sensitivity of about 90% in the detection of polyps > 1 cm. But what there is to be said against virtual colonoscopy as a routine examination is the need for bowel cleansing with an oral lavage and the high costs due to a long examination and evaluation time. The capsule endoscopy is a very interesting new imaging technique for the diagnostic evaluation of small bowel diseases. The capsule endoscopy is superior to push-enteroscopy, the gold-standard until now. But it is not clear, whether there is change in therapeutical procedures due to the results of the capsule endoscopy and whether the high costs for the examination are justified. The contrast-enhanced sonography improves especially the detection and characterization of solid liver lesions and some CT- and MR-examination will be unnecessary in the future.
在过去几年中，内窥镜、放射和超声成像技术有了很多发展，例如虚拟结肠镜检查、胶囊内镜检查和超声造影。磁共振或计算机断层结肠成像在检测直径大于1厘米的息肉方面具有约90%的高灵敏度。但是，虚拟结肠镜检查作为常规检查存在的问题是需要通过口服灌洗进行肠道清洁，并且由于检查和评估时间长而成本高昂。胶囊内镜检查是一种用于小肠疾病诊断评估的非常有趣的新成像技术。胶囊内镜检查优于推进式小肠镜检查，而推进式小肠镜检查是迄今为止的金标准。但尚不清楚由于胶囊内镜检查的结果治疗程序是否会发生变化，以及检查的高成本是否合理。超声造影尤其改善了肝脏实性病变的检测和特征描述，未来一些CT和磁共振检查将不再必要。
