I'm not engaged in obtaining images, so I don't have any details about the images. I wonder the method which you commented can be applied to images I already earned. If it's not, is there any way to recover SNR after image scanning? Thanks, Youngmin Huh. 2012/11/13 Bruce Fischl

Hi, 3D SPGR sequences were used. (TR=22, TE=4, thickness=1.4, FOV=240*240, FA=40) If the artifacts are due to B0 distortion, I wonder how I can fix it. Thanks, Youngmin Huh 2012/11/12 Bruce Fischl > Can you give us the acquisition details? I suspect this is not noise, but > rat

se options work for some images and don't for others. And, 3D SPGR sequences were used. (TR=22, TE=4, thickness=1.4, FOV=240*240, FA=40) 2012/11/12 Bruce Fischl > Can you try it without the expert opts? And what sequence is the data? > > > > On Nov 12, 2012, at 3:35 AM, yo
