Accelerated 3D T2 mapping with a MESE sequence

Accelerated 3D T2 mapping with a MESE sequence

Hello everyone,

We’re excited to announce the release of a custom MRI acquisition sequence for Paravision PV6.0.1 and PV360.3.5 and PV360.3.6 recently published in MRM : https://doi.org/10.1002/mrm.30146

This sequence implements a 3D T2 mapping method with a Multi-Echo Spin Echo sequence and an advanced subspace reconstruction.

You can find all the necessary resources to perform the reconstruction on GitHub : PAPER_subspace_MESE

Key Features:

  • Fast 3D T2 mapping: In-vivo T2 mapping of the brain with isotropic resolution of 156um in 25 minutes
  • Subspace reconstruction: Speeds up data acquisition by a factor of 8 using the prior knowledge of the temporal behavior of the signal evolution

Reconstruction: Reconstruction is performed offline from the rawdata with a dedicated Julia package using either MRIReco.jl or BART.

Notes

This package is still a Work-In-Progress : Contributions, feedback, and questions are welcome on the GitHub repository.

Feel free to explore, test, and share your experiences with this advanced sequence!

Best regards,
