Phase Encoded Motion Artifact 
Quick Overview
Please note that there are different common names for this artifact.
Artifact Information
NAME
Phase encoded motion, motion, phase effect
DESCRIPTION
Blurring and ghosting
REASON
Movement of the imaged object
HELP
Compensation techniques, more averages, anti spasmodic, presaturation
This artifact is caused by movements of the patient or organic processes taking place in the body of the patient. The artifact appears as bright noise, repeating densities or ghosting in the phase encoding direction.
mri safety guidance
Image Guidance
There are different solutions for reduction of phase encoded motion artifacts.
Cardiac and respiratory gating, breath holding, sedation of the patient, presaturation pulses for flow artifacts (e.g. arterial pulsation, breathing), fast imaging sequences, etc.

Case Study 1 :
The repeating structures oriented in phase direction occur as a result of the motion during acquisition of the sequence. This is caused by breathing and peristaltic of the patient.
 
Case Study 2 :
The artifact appears as bright noise in this image.
