material with 'zero' magnetic susceptibility
Does anybody know some material, that is still easy to machine, better non-conductive and - most important - has a susceptibility close to zero. Is there composite materials that are especially made for such purposes?
I know that coils for NMR are usually made like this, but I'm looking for some material that I could make a whole NMR probe out of. It should be non-conductive, because I don't want eddy currents.

thanks in advance, Karsten

Sialography
Hi,
you can take a strong T2 weighted MRCP or similar sequence with smaller FOV. For an overview one thick slice in sagittal or transversal direction and for more details a 3D sequence with thin slices and higher matrix. For better visualization a sour (lemon) juice can be given before the examination.

Sialography
Hi anybody,
who can give me a sialography protocol for a Signa Infinity 1.0T, or an advice how to create
a good one?
Thanks in advance
Lee

coil configuration
I am using a GE signa 1.5T scanner. I want to use my surface coil to transmit, and use body coil to receive signal. Does anyone knows how I should setup the coil configuration file, and tune the system?

Black Blood MRA
I have questions about black blood MRA sequences. Which range of application does this technique have? I have heard also cine black blood imaging is possible.
What is the advantage of black blood cine over standard bright blood cine?
