Hi  
I would like to ask you about the T1 mapping acquisition, using 3 separate series (3D LAVA) with different flip angles, but the T1 mapping module only recognizes “MultiVolume”. How can I “make” MultiVolume from my separate series?

Also, please let me know if there are other reasons why T1 mapping cannot be calculated.

Thanks!
