| Muscle shading in 3T Images |
We are using a 3T GE scanner to image axial slices of human thigh muscle for the purpose of quantifying muscle volume. rnrnProblem: Our images have been presenting some shading at the top and bottom of each slice. We have tried everything we can think of to get rid of this shading but have not been sucessful. rnrnI have attached a representative image and would love some feel back. rnrnThanks so much for attempting to help us out.

| How does TE affect DWI acquisition? |
I never tried to shorten only the echo time while keeping all other parameters the same, but I would expect a change in SNR and artifact appearance. I would use parallel imaging methods to get a shortest possible echo time. Parallel imaging provides DWI with shorter echo trains associated with further reduction of the echo and repetition times, which reduces susceptibility effects and also image blurring. Additionally, the shorter echo time may lead to changes in ADC measurement.

| How does TE affect DWI acquisition? |
Hi folk! Just a breath question: how does TE affect conventional sequence (single shot SE-EPI) for DWI acquisition? In particular, how would two acquisitions differ from each other if acquired with TE=90/106ms respectively (being equal all the other parameters, i.e. TR=11s, same FOV, …)? Thanks for any opinion you will give me. Danilo.

hi buddy
in general,surface coils are designed for receive signals only and have no fuction of transmit

All your parameters will be the same in a 3T as in the 1.5T except for the T1's TR. T1 TR is 700 to 1300.
