| Please recommend materials sensitive to T1-weighted MRI |
Dear all,
I am looking for materials (regardless it is in liquid or solid status) that are sensitive to T1-weighted MRI. On a MRI image, the material has to be white (very bright). Thanks in advance,
Cindy

| Feridex/endorem and bone MRI |
Some experiments with superparamagnetic contrast agents such as Feridex/Endorem with labeled cells showed a black appearance on T2 weighted sequences, which was easy to see. The less dominant T1 effect, bright on T1 weighted images was more subtle. (I found this also interesting http://www.nature.com/nm/journal/v7/n11/full/nm1101-1241.html and the article 'MR and iron magnetic nanoparticles. Imaging opportunities in preclinical and translational research' on http://www.tumorionline.it/cerca.php )

Hello, Just wondering if anyone has a 16 channel Hitachi Echelon and how the images were looking.
Thanks, Keith

| New type of job for CT/MR Tech. |
I've done lots of reconstruction work with Vitrea and the Siemens Leonardo workstation. My impression is that being a good reconstructive tech takes technical know how but your product (images)are heavily influenced by your creativity. Thouroughput is greatly improved with sufficient software knowlege too.
Being quick and skilled at 3D recon does take time and experience. Can you do it, yes.
I'd be really careful about jumping into a serious job and being thrown like 40 cases a day or something like that. If they are willing to work with you than it's good oportunity.

Does changing the gradient mode from "fast" to "whisper" have an effect on the image quality? I just did a PD FS on a knee and compared two sequences that were exactly the same except for one was "fast" and the other was "whisper", which also changed the TR and TE very slightly (TR from 1970 - 2100 and TE from 29 - 31). The whisper sequence was noticeably lower quality and I can't figure out why.
