Zeev and Luis, Zeev, Gadolinium is used on T1-weighted images on which fat is bright. Because gadolinium is bright on T1 wighted images, the problem is that small enhancing tumors may be difficult to see in a sea of fat (polar bear in a snowstorm). This is the main reason why fat suppression was developed. Luis, is, with all due respect, incorrect about the fat suppression working well on ANMR device, according to two sources I have. However that info is old and I hope for stockholders that it is now improved. Because the chemical shift of water and fat is field dependent, separating the two peaks at 0.5T is very difficult. Luis, I think you are confused about what it is that ANMR AKA CAPRIUS can do in samll fields of view. In an ancient post you suggested that they can increase the filed strngth in small fields of view. I don't think that is true. They may be able to improve homogeneity in small fields thereby allowing peak separation to an extent but I would be surprised if the magentic field can actually be increased in subsections of the magnet. Sounds like alchemy to me. Regards, Jim
