| MRI Claustrophobia Interview Request |
Roger,
Claustrofobia is difficult topic, real claustrofobic patient won't enter the room...and thus won't experience MR.
Interesting question is how the environment surounding the actual MR, influences this behaviour (Ambient Experience). Also consider looking at High Field Open MR systems (1.0T).
Cheers

| 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...

| MRI Claustrophobia Interview Request |
My name is Sion Emlyn Rogers, I am currently a student at the Columbia University Journalism School
I am doing a piece on MRI Claustrophobia and how people cope with it. I am looking for people who have experienced this condition who would be willing to be interviewed (this is a print article).
I would ask them to describe the experience, how it affected them, do they feel reluctant to be scanned etc.
Many thanks
Sion Rogers

| scan matrices and steps |
It means that the matrix is variable, so you can choose to have 256, 260, 264 etc matrixes. This is than again part of how advanced the fourier transformation algorithm is.
Cheers
BTW Matrixes are just a number, and actually say nothing at all regarding resolution...yess FOV devided by matrix gives you a pixel size which is actually the interesting part.
