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.
I am trying to get better at reading knee MRI's. I would like to know which protocols are best for evaluating meniscii, collaterals,cartilage, cruciates, bone marrow signals. Please advise.
our MRI machine is open 0.2 tesla in which parts of the body it is realiable to examine with, is there special desigend coil for leg examination.can i use knee or brain coil.
thanks
