We propose a new QSM algorithm, namely multi-scale dipole inversion (MSDI), which builds on the nonlinear MEDI (nMEDI) framework incorporating two additional features: (i) improved error control through dynamic phase-reliability compensation across harmonic scales and (ii) scale-specific use of the morphological prior. MSDI is the first algorithm to rank in the top-10 for all performance metrics evaluated in the 2016 QSM Reconstruction Challenge. It also demonstrates lower variance than nMEDI in a reproducibility test.
How to access this content:
For one year after publication, abstracts and videos are only open to registrants of this annual meeting. Registrants should use their existing login information. Non-registrant access can be purchased via the ISMRM E-Library.
After one year, current ISMRM & ISMRT members get free access to both the abstracts and videos. Non-members and non-registrants must purchase access via the ISMRM E-Library.
After two years, the meeting proceedings (abstracts) are opened to the public and require no login information. Videos remain behind password for access by members, registrants and E-Library customers.
