Belinda,
It would be helpful if you would add a photo, even if you take a cellphone photo of your screen and blot out the name.
You did not say, but is this a new problem?
In general, if one orientation looks worse than others, you may have a magnet shim problem; you can crudely test this yourself by using a cylinder type phantom and doing an identical scan in three planes. A shim problem would affect T2's more than T1 or PD images also.
There is always a possibility that your sequences have changed without you realizing it too; check this even if you don't know how that would have happened.

I work on GE excite open speed. On lumbar spine t2 axials, it appears like the coil looses signal and makes image dark and grainy. The coil gives good signal on the other sequences and tests good when engineer has tested it. The sag t2 is bright like it should but ax is dark. Any ideas why?

| new job in MRI |
Hello, I have happily accepted a job working in MRI and CT having worked in just CT. I have a few months until I start and was wondering if anyone could recommend a few good books regarding basic physics and pulse sequences to get me started :) I will be working in a hospital with alot of cardiac work using seimans MRI scanners many thanks, Rob :)

Dears!!
I try to understand why TIRM have a long TR and long TE ( value of T2 image ) but sequences bring a T1 mark
Thanks!!!

I think it's better to plan both ureters, put the pack of slices exactly coronal on an axial abdomen slice including both kidneys, take care on a sagital slice to give an angle parallel to spine but including the bladder and the space behind it, use foldover direction (siemens) or Rfov 1 (GE), fov 400-450, sl thick 0.80-1mm, open the 3d slice pack as much as needed, use navigator-pace (siemens) or triggering (GE).
A preparation of diet is needed some times, additional sequences (haste, fiesta, vibe+iv or lava+iv contr) are necessary.
