Virtual chromoendoscopy is used to enhance surface patterns and colour differences. One type of virtual chromoendoscopy is the Fuji Intelligent Colour Enhancement (FICE). Although widely applied in conventional endoscopy, data on FICE application in capsule endoscopy are limited. Furthermore, the validity of Blue filter (feature of RAPID(®) software) has not been examined. AIM/S: We aimed to qualitatively evaluate the use of FICE and Blue filter enhancement, in images of lesions obtained during small bowel capsule endoscopy, comparing them with similar, conventional (white light) images.
A total of 167 images (6 different lesion categories) obtained from 200 capsule endoscopy examinations. Two gastroenterologists examined the images with white light, FICE and Blue filter in regards to the visibility of blood vessels, the contrast of the mucosal surface, and the demarcation of lesion borders. The agreed scores were: improved, similar, worse. Inter-observer agreement was calculated.
For all lesion categories, Blue filter provided image improvement (compared to white light) in 83%, (inter-observer agreement: 0.786). With FICE 1, improvement was observed in 34%, worse image in 55.9%, (inter-observer agreement: 0.646). With FICE 2, improvement was observed in 8.6%, worse in 77.5%, (inter-observer agreement: 0.617). With FICE 3, improvement was seen in 7.7%, worse in 79.9% (inter-observer agreement: 0.669).
Comparing with FICE, Blue filter offers better image enhancement in capsule endoscopy.
虚拟 chromoendoscopy 用于增强表面图案和颜色差异。虚拟 chromoendoscopy 的一种类型是 Fuji Intelligent Colour Enhancement (FICE)。虽然在常规内窥镜中广泛应用，但在胶囊内窥镜中应用 FICE 的数据有限。此外，Blue filter（RAPID(®) 软件的功能）的有效性尚未得到检验。
目的/方法：我们旨在定性评估 FICE 和 Blue filter 增强在小肠胶囊内窥镜获得的病变图像中的应用，将其与类似的常规（白光）图像进行比较。
总共对 200 次胶囊内窥镜检查中的 167 张图像（6 种不同病变类别）进行了分析。两名胃肠病学家使用白光、FICE 和 Blue filter 检查图像，评估血管的可见性、黏膜表面的对比度和病变边界的界定。评分结果为：改善、相似、恶化。计算了观察者间的一致性。
对于所有病变类别，Blue filter 提供的图像改善（与白光相比）在 83%的情况下，（观察者间一致性：0.786）。使用 FICE 1，改善的情况为 34%，恶化的情况为 55.9%，（观察者间一致性：0.646）。使用 FICE 2，改善的情况为 8.6%，恶化的情况为 77.5%，（观察者间一致性：0.617）。使用 FICE 3，改善的情况为 7.7%，恶化的情况为 79.9%，（观察者间一致性：0.669）。
与 FICE 相比，Blue filter 在胶囊内窥镜检查中提供了更好的图像增强效果。
