Quick Overview Please note that there are different common names for this artifact.
DESCRIPTION
Static on the image
REASON
Electromagnetic emissions
HELP
Shielding, eliminate the factor of disturbance
RF noise, which often appears as static on the image, can be caused by a medical device located anywhere in the MR procedure room.
RF noise is a result of excessive electromagnetic emissions from the device that interference with the proper operation of the MR scanner.
The interference is attenuated and aliased in the frequency direction.

Adiabatic RF pulses are amplitude and frequency modulated pulses that are insensitive to the effects of B1-inhomogeneity and frequency offset (conventional RF pulses used in MRI are only amplitude modulated). Due to an extended application time adiabatic RF pulses are mostly used in NMR imaging applications. | | | | • View the DATABASE results for 'Adiabatic Radio Frequency Pulses' (2).

DESCRIPTION
Image non-uniform
REASON
Signal too intense
The received radio frequency signal is too strong, parts of the signal get lost by converting from analog to digital, resulting in a washed out image.
