Downloadable Sequences

Currently, the multi-echo MPRAGE with vNavs is being distributed for Siemens scanners running VB17a as Siemens WIP 711. MGH is also making available versions of T2 SPACE, and T2 SPACE FLAIR that use embedded vNavs to correct motion every TR. These sequences are available by special agreement for certain Siemens scanners running VB17a. If you are interested in using these sequences, please contact tisdall@nmr.mgh.harvard.edu.
