I had an MRI yesterday and I have alot of metal in my neck due to extensive surgery such as anterior fusion from c4 to c7. Yesterdays results indicate I have atrophy of the spinal cord from C4-5 to C7 with a thin cord and high signal compatible with myelomalacia. Herniation of C3-$ that compresses the spinal cord. Central protrusion of the C2-3 and C7-T1 discs. My question is. My neck burns as if on fire inside. Is this something that will go away? I have and do have severe pain 24/7 but I've never had this kind of pain. If possible please email me at oceansmove07@aol.com if you know what's happening. Thank you for any help you may have and I wish everyone a lighter today, a brighter tomorrow and a future filled with joy and happiness.

| T1 FAT SAT PRE AND POS GADO |
The contrast agent causes this difference. Contrast agents reduce the T1 time in tissues where they have accumulated depending on blood flow and vascular permeability. Caused by this, tissues after an application of contrast agents will differ in shortening of the T1 time, and the same imaging parameters result in other image appearance.
Some helpful links for musculoskeletal imaging and Fat Sat:

Can anyone tell me what FOV is used on a 2 year old whole body scan? , On an adult whole body scan ? , and how many table moving stations are needed for an adult whole body scan? I am doing a coronal Stir,T1 FFE coronal and a SSFSE T2W coronal.

| 3T imaging parameters |
At 3T the T1 time is longer (so the TR should also be longer) and the T2 time is shorter (TE can be shorter). However, when we got a 3T machine we tested different TR and TE's and found out that in practice the useful range don't has a big difference from that of a 1.5T MR system.
The contrast looks a bit different - that's normal.
In addition, ask the manufacturer.
There are a lot of other parameters that affect the contrast in 3T.
Hope this will help
