We know about that, but what about saving the phase at the same time? This is what we were having difficulty with. -----Original Message----- From: FSL - FMRIB's Software Library [mailto:[log in to unmask]] On Behalf Of Daniel Schwartz Sent: Wednesday, December 19, 2007 12:50 PM To: [log in to unmask] Subject: Re: [FSL] Using Siemens Trio field maps in FUGUE Getting the Siemens 3T Trio to save the magnitude images is a checkbox in the protocol... just flip through the tabs until you see a "save magnitude images" box. It will give you two volumes of magnitude images, one for each TE, although I'm not exactly sure that fugue needs these mag images at all. At least, that's what it does on our Trio. Does anybody have any good ideas about what the UNITS are on these phase field maps (3T Trio)? -Daniel Daniel Schwartz, CIC Functional Brain Imaging Lab Oregon Health & Sciences University 3181 SW Sam Jackson Pk.

There is a Siemens filed mapping protocol that provides two image files. The first looks like a field map image, while the second looks like a magnitude image. However, when I submit these files to FUGUE via the MELODIC gui the results are strange, (It appears as if the brain is on fire!). I am encouraged by a report that something very similar has been done (see: http://users.fmrib.ox.ac.uk/~kylep/kyles_papers/abstracts/ismrm_def_abstract _submitted.pdf). I would be grateful for any insights! -Kent Conover
