FSPGR

[scottgloverjohnson]

I work at an animal hospital and I'm currently in an MR program. No protocols have been set up for our magnet that are appropriate for the variations in patient size/tissue differences, so I have been trying to set them up as best I can.

We have a 1.5T GE Brivo- the radiologists here have been interested in reformattable 3d acquisitions for T1 weighting. I suggested the FSPGR for better grey/white contrast, as our T1 FSE's have tended to look pretty washed out. However, when I acquire the images (15 lb patient, 8 channel knee coil, .8mm slice, 224x224, 180mm FOV, 2 NEX, out of phase TE, 30 FA), There is an sometimes an awful gibbs artifacts on the reformats! What might be the cause for that? Is there anything I can do to resolve this?
