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
