Common Sources of MRI Artifacts
Artifacts arise from patient motion hardware issues and from sequence related factors and identifying the source such as gradient instability patient movement or susceptibility effects guides targeted corrective actions
Sequence Optimization and Parameter Tuning
Adjusting sequence parameters such as bandwidth echo time and parallel imaging factors and using motion compensation techniques and navigator echoes reduce artifacts while preserving diagnostic contrast and spatial resolution
Hardware Checks and Preventive Maintenance
Regular hardware checks coil testing and timely firmware updates and vendor supported calibrations prevent many artifact sources and documenting artifact trends supports proactive service and reduces repeat scans
