Hello,
I am trying to the following parameters into a arterial spin labeling analysis and I want to make sure that I am entering my information correctly.
I am using a Siemen's Picore QT2 sequence and have the following details listed in my protocol...
TR = 3000 ms
Inversion Time 1 = 700 ms
Inversion Time 2 = 1600 ms
Saturation time = 1400 ms
Slices = 22
My TE = (3000 - 700 - 1600) / 22 or 31.8181
Is this correct? I just want to double check that I am entering in the correct TE details for this type of ASL sequence.
In addition, does anyone know how I would obtain the following parameters?
How does someone obtain the labeling efficiency and what is "TimeShift"?
Thanks for any help you can provide
