Abstract
Blue laser imaging (BLI) (Fujifilm Co., Tokyo, Japan) is made from two types of lasers with wavelengths of 410 and 450 nm. BLI is a kind of narrow-band light observations. This mode enables us to observe the detailed surface pattern and vessel pattern for diagnosing JNET classifications for colorectal lesions. Although it is originally performed with NBI, the JNET classification can be used with BLI in similar to NBI; we previously demonstrated the high consistency in the findings of NBI and BLI magnification. Typical T1b cancers show loose vascular area and amorphous surface pattern. In those tumors, surface structure seems destroyed. However, some T1b cancers remain surface structures and show irregular vessel pattern and surface pattern. In this paper, we review the efficacies of BLI magnification for T1 cancers.
