| 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.

| Why reset relative SNR value on GE Optima? |
Hello, if anyone works on a GE Optima, or any other MRI that has a relative SNR reset button during scan, please explain to me the purpose of this button. I see that it brings the relative SNR back up to 100 percent, but it can't actually be improving the image quality, can it? I just don't understand what the button is actually doing. The manual states that pressing the button brings the value to 100. Clearly. But what is actually happening other than making me feel better about my scan. Thanks.

| door alarm/ MRI pauses if door opens |
Hello all. I am a engineering student that is studying everything that I can. I came across something that said MRI's are enclosed in a room (duh) but when the scan is going the door is "armed" so if it is opened the scan pauses. Is this true for all MRI's? I work in a small imaging center and when I asked the tech there he gave me a funny look and said go back to work. Can you help? Can you tell me which MRI system that you are using and whether or not it when the door opens the scan will pause or stop. If the scan stops is the series lost? is everything? or can you pick up where you left off. Thank you for your assistance. If you have any other information about MRI's pausing during scans, stopping, saving image quality, and you are willing to share please feel free to share.
I was bold in the pursuit of knowledge, never fearing to follow truth and reason to whatever results they led, and bearding every authority which stood in their way.

GE SWAN sequence parameters. Does anyone know how to make this faster, but not effect image quality?
