Proton Density and FOV
I've been told that proton density sequences don't work well with a large field of view. (approx 350-400) Is this the case, and why?

Thanks in advance,

Annika

fluid PD vs T2 weighting
Can anyone explain me, why - considering SE sequences with the same TR - fluid in a PD weighting (short TE) should have less signal than in a T2 weighting (long TE)? eg:
Fig 10, p 1397; radiographics resident tutorial: contrast mechanisms in spin echo MR imaging; Radiographics 1994; 14; pp 1389-1404

I would expect that the signal intensity of any tissue (regardless of it Proton density of T2-relaxation time) should decrease with increasing echo time.

Thank you

MRI Marker
There is a company which make MRI skin markers but they are poor for fat-sat sequences.

I have emptied oil capsules of fish oil and instead added my own ingredients into them, according to the specific sequence I use.

Try:

*Pure Water
*V V Dilute MRI contrasts

MRI Marker
Are there any MRI markers that are visible on all sequences, small, flat, cheap and self-adhesive?
Vitamin E or fish oil capsules work mostly well, but the signal is suppressed on sequences with fat saturation.
To mark a small region they are too big and
dent the skin where fixed.

Thankful for every suggestion and friendly greetings to all.
