i-scan Technology

i-scan consists of three different image algorithms: surface enhancement (SE); tone enhancement (TE); and contrast enhancement (CE). The three modes (SE, TE and CE) are arranged in series, therefore, it is possible to apply two or more of these modes at one time. Switching the levels or modes of enhancement can be performed on a real-time basis, without any time lag, by pushing a scope button, enabling efficient endoscopic observation.

i-scan & HD+

Currently available high-resolution endoscopy systems (high definition or HD) achieve a resolution of 1400x1080 pixels. Combined with conventional or virtual chromoendoscopy, preliminary clinical data indicate that the technical advancement of HD endoscopy is a decisive element of improved diagnostic investigation of early forms of cancer, and is able to exert an immediate impact on the prognosis of the disease for patients. In a large retrospective study Buchner was able to show, in 2430 patients, a significant rise in the detection rate of adenomas (HD 28.8% vs SR 24.3%, P = 0.012) by HD endoscopy1.

Recommended Settings

Based on current consensus, these are the recommended settings for the three i-scan modes: (i) i-scan 1 for detection of lesions. (ii) i-scan 2 for characterisation of lesions. (iii) i-scan 3 for demarcation of lesions.

Squamous cell cancer of the oesophagus

Early squamous cell cancer of the oesophagus is easily missed. In these flat lesions, it is also difficult to identify the margins of the tumor. In this patient i-scan was used to assess the extension of the mucosal cancer before performing endoscopic submucosal dissection.

Gastric cancer

This video sequence demonstrates to observe characteristic of surface pattern with i-scan SE then switch to i-scan OE to observe vessel pattern. i-scan OE brought up better assessment of vessel as compared with chromo endoscopy. Following pathological result concluded mucosal cancer 8mm in size.
