Improving MEDIC/MERGE/M-ffe and GRE/FFE image quality
I work on an Ingenia Elition Philips scanner. I'm having trouble with Axial C-spine sequences for both M-ffe and FFE. On the M-ffe there is always motion in the cord and the contrast is poor. With the FFE the closer we get to the lungs the worse the quality becomes. There is usually loss of signal and the image doesn't look uniform. I've tried a bunch of different parameter combinations to try giving it more signal and contrast while decreasing the motion in the cord but it never seems to look that good. Any suggestions would be appreciated.

MRI contrast side effects
Hi hoping you can help. I had a brain mri w and w/o contrast and mra. Weird skin sensation now like tingling and also some shaking. Maybe the shaking from anxiety? Just afraid of contrast side effects

Main differences in GE 9X and 12X software for Techs?
What are the main differences between the two mentioned platforms? What would a technologist have to be aware of when switching from a 9X system to a 12X system? Anyone have an literature I could access?

thanks,

6-1.5T MAGNETS, DIFFERING GRADIENTS
What parameter, if any, can compensate between magnets of equal field strength but very different gradient strengths? A T2 FAT sequence on one magnet can look very different on another magnet using same parameters.
