 CAUTION
Local variation in the sensitivity of local coils!
Continuous fluctuations in MR image brightness
◆ Whenever possible, use a local coil with transmit
characteristics that are more suitable for the field of view
desired.
◆ Use the normalization filter.
 CAUTION
Static and/or stationary brightness errors on the LCD monitor
due to aging!
Incorrect diagnosis
◆ Scroll through the images to ensure that the MR image does
not show differences in brightness, spots, or cloudiness and
check bright objects for afterglow.
◆ Keep your eyes always in central monitor position with a
vertical view angle towards the screen surface for best image
quality.
 CAUTION
contrast
Inhomogeneous RF field!
Asymmetry of contrast in the MR image
◆ Whenever possible, use a local coil with transmit
characteristics that are more suitable for the desired field of
view.
