Cerebro Spinal Fluid Pulsation Artifact 
Quick Overview
Artifact Information
NAME
Cerebro spinal fluid pulsation
DESCRIPTION
Ghosting
REASON
Inconsistencies in phase and amplitude
HELP
Flow compensation, cardiac triggering
Pulsatile cerebro spinal fluid flow produces ghost artifacts that are superimposed in the image.

Image Guidance
Flow compensation should be used to reduce these artifacts. This applies an additional gradient to eliminate phase differences for both stationary and moving spins at the echo time. At TE no phase differences is measured. If flow compensation is applied and there are still flow artifacts, cardiac triggering is an additional option to reduce these artifacts.

Case Study 1 :
The artifact is seen as a small dark band between the cervical bone and the spinal cord.
 
Case Study 2 :
The same slice scanned with flow compensation shows the artifact reduction.
