3T imaging parameters
Hi
Am looking for the ranges of acceptable TR and TE's for standard spin echo and gradient echo sequences on a 3T.
Does anyone know these or tell me where I can find this info?

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

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.
