[Research on type selection index of electronic chromoendoscopy system].

The technology of electronic chromoendoscopy consists of narrow band imaging (NBI) and fuji intelligent chromo endoscopy (FICE). The two skills help distinguish between normal mucous membrane and focal zone and raise the detecting rate between the abnormal proliferation and early cancer. Therefore, the exploring research for type selection index of the two technologies and systems will be beneficial to the choice of the highest cost-effective endoscopy system and to the avoidance of wasting resources. By comparing all the indexes, and with purpose of clinical usage, NBI system has advantage over the FICE system. But with purpose for scientific research, the FICE system will be the better choice.
