Cor STIR

[Barrymagnetic]

How can I reduce the scan time when imaging with a STIR protocol? I'm using a GE scanner by the way.

I've been shown to increase the TR until the max # of slices equals the total # of slices. This will reduce the scan time into an acceptable range usually. The problem arises when the TR approaches 6000 ms or more. What other variables can be adjusted to keep the TR lower than that? It has been suggested to set TE in the middle of the min/max settings. Reduce number of slices? Reduce slice thickness? Adjust ETL? Other ideas?

Thank you for any and all help!
