flow arifact
I wonder if it has anything to do with the placement (location) of the wrist within the scanner. Assuming that your using the scanners coil as a reciever- Are you scanning close to the edge of the scanner? The sat band also has to be within the FOV/limits of the scanner.

I suggest trying different locations in the scanner (or using a smaller FOV). It would be strange if you had artefacts in some writs and not in others.

flow arifact
Hi Everyone,

I had experienced flow artifact while taking Axial images of a wrist on 1.5T Siemens MRI scanner. I was using a presaturation band to block the arterial blood flow but it was not making any difference and the artifact was still there.

The phase direction was A-P, and the artifact was in this direction.

Please help me to get rid of this artifact.
