Common artifacts in MRI due to the presence of metallic implants, and methods to reduce them, as described in detail in the text. Standard methods are widely available, while more advanced methods are generally in research phases.

Artifact	Standard Methods to Reduce Artifact	Advanced Methods to Reduce Artifact
Signal Loss from Dephasing	Spin Echo or Fast Spin Echo (FSE/TSE/RARE)	Ultrashort Echo-Time Sequences, SWIFT
Failure of Fat Suppression	Use of STIR imaging, or Dixon techniques (less effective)
Geometric Distortion	High readout bandwidth	View-Angle Tilting Field-map based corrections
In-Plane Distortion (Pile-up and Signal Loss)	High readout bandwidth Swap frequency/phase	View-Angle Tilting
Through-Slice Distortion	Non-selective Imaging Thin slices	(See below)
All distortions	(See Combinations above)	Multi-spectral Imaging (MAVRIC, SEMAC, etc)
