some times mri is with radiotracer or contrast , does mrs sometimes require radio tracer or contrast or something similar? in vivo or laboratory.

Could you clarify what MRS stands for? I am not familiar with the acronym.

Magnetic resonance spectroscopy? As in NMR or ESR? those don't require a radio tracer. In the lab anyway.

 

Some people do use gadolinium NMR contrast agents though for NMR. It increases the j-coupling values and spreads out chemical shifts.

 

*I think gadolinium, someone help me out here.

I thought it might be another term for NMR, but I wasn't sure as I've not seen it called that before.

 

And back in the 80's people used to use lanthanides to spread out chemical shifts. With the advent of 2D spectra and things like NOESY, it's become more or less obsolete.

i think its nmr, nmri, nmrs..... nuclear magnetic resonance, nuclear magnetic resonance imaging, nuclear magnetic resonance spectroscopy
