| fluid PD vs T2 weighting |
The truth is basicley that different tissues have different relaxation times, the signal of fluid last longer than fat in a T2, so it appears bright.
But also with a "short" TE of 30ms you can already achieve a high signal of fluid, but this is highley dependend of the TR. A long TR - 5000ms - will give you a high signal of fluid. But scantimes won't be acceptable...
