Standard sequences @ 3T

GABA edited spectroscopy

!!!!!!!!!!!!UNDER CONSTRUCTION!!!!!!!!!!!!!!!

3T

We use a patch from Richard Edden (John's Hopkins University), which contains a MEGA-PRESS sequence for 3T. For more information on the development of this patch, see: www.gabamrs.com.

Please visit this website first for an explanation of the method used, before you start your experiment.

If you have any remaining questions after reading this Wiki page, please contact Anouk Schrantee.

The patch

The patch needs to be loaded with Select Patch and is currently called R5_4 MEGA. Please make sure you read the instructions on the do's and don't's of using patches here.

How to acquire GABA data

There are currently two implementations to scan GABA working on the 3T.

- GABA_68_PAR: without macromolecule suppression

- GABA_80_PAR: with macromolecule suppression

The HERMES implementation is not yet working.

The analysis software

The developers of the patch also provide an analysis toolbox to analyze your spectroscopy data. For more information on this, and examples, please see: www.gabamrs.com. It exists of a series of Matlab scripts, but it can easily be called from the command line in Matlab - no need to change the scripts for the standard implementation. The manual of how to analyze your data is also in the folder mentioned below.

Important: You can download Gannet on their website, but we have optimized the analysis toolbox for the data that we acquire at the Spinoza, so please use the version you can find here: Gannet 2.0
