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.

Crohn`s disease ileum

Aphthoid ulcers of the terminal ileum are a typical finding in Crohn’s disease. As seen in this video, contrast and tone enhancement makes even subtle changes easier to spot.

Laterally spreading tumour

In this patient with a laterally spreading tumour granular type i-scan was used to get a clear idea about the polyps pit pattern. As a pit pattern type IV was found, indicating a benign lesion, we proceeded to resect the lesion by means of endoscopic mucosal resection.

Radiation Proctopathy (RP)

RP is a chronic condition that has a significant burden on patients quality of life and healthcare. This clip shows how i-scan 2 helps to highlight the vascular lesions in detail in a patient with symptomatic bleeding and allows targeted YAG laser treatment to the lesions. The vascular areas are not prominent on HD WLE or even i-scan 1 but by switching to i-scan 2 thermal therapy can be directed to the abnormal areas.
