| 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.

| MRI contrast side effects |
Unless you are on cancer medication, there are no delayed side affects from contrast. It is a heavy metal and some is retained.

We scan on a 3T, our protocol is 22 minutes. T2 cor/sag, T1 full pelvis, Diffusion, post contrast dynamic imaging.

| What does this mri report mean |
Small developing vertical cleft along the radial side of the membranous TFC disc fibers, best seen on image 11 series 5. There is no evidence of contrast transit into the distal radioulnar joint. The remainder of the TFC disc is intact and grossly unremarkable.
Intact intrinsic ligaments. There is no widening of the intervals. There is no contrast in the midcarpal compartment.
Increased interstitial signal within the ECU tendon is likely due to tendinopathy and a developing longitudinal split. The remaining tendons are grossly unremarkable.
Normal caliber median and ulnar nerves.
Minimal generalized wrist osteoarthrosis with minimal to mild chondromalacia, small intraosseous cysts and minimal osteophytosis.

| Contrast on an 3T |
Studies (for example http://pubs.rsna.org/doi/full/10.1148/radiol.2373041672 , http://pubs.rsna.org/doi/full/10.1148/rg.287075154 ) suggest that contrast enhancement of gadolinium is increased at higher field strengths. That can be used to lower the dose or receive higher contrast effects. It also depends on the contrast sensitivity of the used sequences and the examined body part.
