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.

What´s this in L3?
I´m a Dutch Physiotherapist and not trained in reading MRI images.
Yesterday my last client brought a CD with MRI-images on his first visit. He experiences a lot of lumbar pain, takes lots of painkillers and had a HNP operation earlier.

There is something strange about L3. Can you tell me what it is?

The doctor only told him there was no reason to think he had neurological problems but never mentioned this.

ETL for a STIR
I prefer a range from 5-12 (but using shorter TE and TR). High echo trains can lead to blurring, image noise and contrast inhomogeneities.
Parallel imaging can reduce the longer scan time of low ETLs; also often 1 NSA is enough for sufficient SNR.

Hope this helps!

Whats the ETL range for a STIR? Assuming 50TE 5000TR 150TI.

Does it follow the T2 parameters? Can someone give me the pros/cons of high versus low ETL?
