STIR and l-spine
we have got new spine coil for our 1.5 T philips achieva scanner. App came in and added new software and protocoal for that. when we run STIR sequence for l- spine with regular size patient, it comes out nice. However, with hypersthenic patient, it comes out very dark, suppressing signal from bone,fat and only shows csf in cord. could it be that TI not optimal for hypersthenic patient?

STIR-TR
Is there a rule regarding what the TR should be for a STIR sequence? If so, is the 'rule' different for 1.5 and 3.0 Tesla?

STIR sequences
I am a little confused on STIR techniques.... I was always taught that you keep your TR down on STIR sequences around 2200 or so, Is this true?

ETL for a STIR
Whats the ETL range for a STIR? Assuming 50TE 5000TR 150TI.

Does it follow the T2 parameters? Can someone give me the pros/cons of high versus low ETL?
