| Regarding recovery and decay [basic phycisc] |
Hi,
I'm not so sure but I think because different physical process are being involved. Longitudal relaxation has got something to do with energy exchange to the environment. Transverse relation occurs because of spin dephasing (magnetic inhomogenity.)

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.

Andre,
You can do a PD sagittal and/or T1 coronal. These two would give you meniscii tears, just magnify them and brighten the image to show the tear. You can also try the T2 STIR coronal to show some swelling and bone contusion. Check with your rad to find out proper protocols.

Please help me to understand the parameter "concatenations" on the Siemens software, both in terms of what the hardware and software is doing, and the trade offs. I'll take anything at this point!
Thanks for your help,
Michael

| Need information/help from MRI Techs |
Allen,
MRI is one of the hardest modalities in my opinion. I would start with getting your radiology degree. It is a good foundation to know what you are looking at. You will need cross-sectional anatomy. The benefit to going into radiology is that you can branch out into multiple modalities. It will be hard to find work for you in MRI unless you have a radiology background. And if you do go into MRI without the education to back you it will be a long frustrating haul. Good luck
