I know this is a really old question but I'm answering so that maybe others might learn.
The scanner you refer to is actually the E Scan (or possibly the E Scan XQ or the E Scan Opera) by Esaote.
You are correct, the flex coil for hips does not give good coverage or good signal. Most of our E Scan customers never use the coil.
A larger problem for hip studies is that the opening in the magnet and the FOV of the magnet severely limits the ability to scan patients of average and larger than average size.
the same can be said of doing shoulder exams on this scanner, in general the images are not met with happiness by the radiologists.

Can someone please help me interpret this horizontal MRI T2 slice? The images are of just behind my eyes. I don't think those black dots are meant to be there... I know that foramen make a black dot but I don't think that there are any foramen where the dots are.

RECENTLY FAILED ACR FOR BREAST IMAGING.
I AM LOOKING FOR A GE SITE FOR ADVICE.
WE HAVE A GE 1.5T HDXT SYSTEM USING 15 XM4 SOFTWARE. OUR COIL IS A GE LIBERTY 9000 8 CHANNEL COIL.
IF YOU HAVE PASSED THE ACR WITH THIS EQUIPMENT AND DO NOT MIND SHARING INFORMATION, WE WOULD LIKE TO HEAR FROM YOU.
ACR REVIEWER REASONS FOR FAILING WAS GHOSTING, CHEMICAL SHIFT ARTIFACT, AND INHOMOGENOUS FAT SAT.
THANKS,
MIKE RT(R)(MR)

| Faster pulse sequences |
Hi,
I have been learning about faster MRI sequences and have two questions
1) With "Fast (Turbo) gradient echo", in which we apply a spoiler gradient, do we not eventually end up with no longitudinal magnetization because TR is always shorter than T1? Hence shouldn't we eventually get no signal at all?
2) in SSFP (Steady-state free precession) we can apply an RF pulse of 90 degrees (in which T1>>T2) to get heart-blood contrast. How is this any different to a standard spin-echo sequence in terms of timing?
Thank you
