The MR image may show system-related artifacts/imaging errors
despite careful preparation.
◆ If the same artifact/imaging error appears repeatedly, document
and submit it to Siemens Service.
 CAUTION
RF-signal interference caused by incompatible accessories e.g.
patient monitoring devices!
Streaks and bright spots in the MR image
◆ Use only accessories tested and approved for the MR system.
◆ Keep the door to the examination room closed.
◆ Vary the bandwidth of the MR sequence.
◆ Whenever possible, use local coils for the MR examination.
 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.
