Causes: Artifacts and imaging errors are listed according to their
source for error:
◾ System-related artifacts/imaging errors
◾ Patient-related artifacts/imaging errors
◾ User-related artifacts/imaging errors, see: Software operator
manual
User-related and patient-related artifacts/imaging errors can be
largely avoided through patient instructions and proper conduct of
patient and personnel.
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
Phasing of MR signal is not set correctly!
Structure is shown in the wrong position
◆ Repeat the measurement for the structure in question by
using a second orthogonal slice and check whether the
position of the structure is reproducible nor not.
System-related artifacts/
imaging errors
Stripe artifacts
