| cervicla axial image t2 and t2* |
hello
every one
may i have question ~
why used for cervical axial t2 star instead of t2 in signa 1.5t ?
and what differnt t2 star between t2 of pathology ..?
umm,, my english is pool,, sorry about that,,
bye..
wating for kindly answer~

| Improving MEDIC/MERGE/M-ffe and GRE/FFE image quality |
I work on an Ingenia Elition Philips scanner. I'm having trouble with Axial C-spine sequences for both M-ffe and FFE. On the M-ffe there is always motion in the cord and the contrast is poor. With the FFE the closer we get to the lungs the worse the quality becomes. There is usually loss of signal and the image doesn't look uniform. I've tried a bunch of different parameter combinations to try giving it more signal and contrast while decreasing the motion in the cord but it never seems to look that good. Any suggestions would be appreciated.

| Query on PROPELLER enhancement |
I looked at an MRI from 2016 I originally had for a tongue swelling to see if it might show evidence for Optic neuritis which I believe I had at that time. I noticed coronal slices show the outer circumference of the optic nerve as especially bright and ragged or irregular along much of the length (both eyes). This looks like donut sign for ON but I wonder if it could be an artefact of the imaging process as it used something called PROPELLER which I believe enhances the image. An axial slice also appears to show the tram track sign. Can anyone comment. I have uploaded a screenshot of just a single coronal slice
See uploaded slice

While planning vertebral discs for axial cuts is there any way to align the slices perpendicularly on coronal plane? Currently I have to manually align them on the vertebral column which is tedious and sometimes erroneous.
I have worked on Siemens Avanto and there is option to select the slice to align perpendicular so that I only have to pay attention to one plane while in Toshiba the task is a bit more complicated. Though there is an option of aligning all slices perpendicularly but it does not work or may be I am doing something wrong.

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?
