Question Posted 02/19/18:
Question about ASL sequence done under ADNI2 (for Siemens 3T Skyra). Can you tell me the "Inversion Time" parameter? (I assume it is something like 1800msec).
I downloaded this protocol file: http://adni.loni.usc.edu/wp-content/uploads/2010/05/ADNI2_Siemens_3T_Skyra_D11_HR_T2.pdf
Unfortunately in the relevant section, I see this information:
Bolus Duration:700 ms
Inversion Time:syngo.MR.ProtBasic.Interop.ValueArray
Inversion Array Size:1
I think this means that the "Inversion Time" is an array of values (with actually only one value for this protocol); and the stupid Siemens protocol export is not smart enough to list that one value!

Thank you for your question to the ADNI MRI Core.
We understand your frustration.
After looking at the scanner itself the Inversion time is listed at 2000.
