5.8 Special light observation
Do not rely on the special light observation method alone for
primary detection of lesions or for a decision regarding any
potential diagnostic or therapeutic intervention.
NBI (narrow band imaging)
If the endoscopic image seems to be dark in the NBI
observation, change to the normal observation. Otherwise,
the examination might not be preformed safely.
Perform the white balance adjustment for NBI observation
after completion of the white balance adjustment for the
normal observation. Otherwise, NBI observation cannot be
performed with a correct color tone.
NBI is an observation method that employs filtered light as examination light.
NBI requires the following equipment;
• CLV-180 light source
• NBI compatible endoscope:
GIF-H180, CF-H180AL/I, GIF-Q180, CF-Q180AL/I, PCF-Q180AL/I,
GIF-N180, BF-Q180, BF-P180, BF-1T180, ENF-V2/VQ, CYF-V2,
CYF-VA2, OTV-S7ProH-HD-L08E, LTF-VH, WA5001

Normal observation and NBI observation can be changed during use.
All mucosal areas are to be viewed using traditional white light.
NBl imaging should not be used as a substitute for a thorough traditional
examination of the mucosa.
1.
Select the NBI mode on the light source using the mode button, and confirm
the NBI indicator of the light source, referring to the instruction manual of the
light source.
2.
Confirm that the NBI indicator on the front panel of the video system center
turns from green to white (see Figure 5.103).

• During NBI observation, bile and residual debris may appear
dark and reddish.
