Journal ArticleDOI
Tracking dynamic resting-state networks at higher frequencies using MR-encephalography
TL;DR: Preliminary results have found corresponding networks at frequencies above 0.1 Hz showed better stability in both spatial and temporal dimensions from the sliding-window analysis of the time series, which suggests the potential of using high temporal resolution MREG sequences to track dynamic resting-state networks at sub-minute time scale.
Journal ArticleDOI
Single shot whole brain imaging using spherical stack of spirals trajectories.
Jakob Assländer,Benjamin Zahneisen,Thimo Hugger,Marco Reisert,Hsu-Lei Lee,Pierre LeVan,Jürgen Hennig +6 more
TL;DR: It is shown that the loss of spatial information is reduced when using a stack of spirals trajectory compared to concentric shells, making a meaningful image reconstruction impossible in the affected areas.
Journal ArticleDOI
Single shot concentric shells trajectories for ultra fast fMRI.
Benjamin Zahneisen,Thimo Hugger,Kuan J. Lee,Pierre LeVan,Marco Reisert,Hsu-Lei Lee,Jakob Assländer,Maxim Zaitsev,Jürgen Hennig +8 more
TL;DR: A novel imaging method for fast three‐dimensional‐MR‐encephalography whole brain coverage based on undersampled, single‐shot concentric shells trajectories and the use of multiple small receiver coils is described.
Journal ArticleDOI
Fine-grained mapping of mouse brain functional connectivity with resting-state fMRI.
Anna E. Mechling,Neele S. Hübner,Hsu-Lei Lee,Jürgen Hennig,Dominik von Elverfeldt,Laura-Adela Harsan +5 more
TL;DR: The intrinsic architecture of mouse brain functional circuitry was characterized here, based on rsfMRI data acquired at 7T using the Cryoprobe technology, and each major functional system was found to have representative hubs that might play an important input/output role and form a functional core for information integration.
Journal ArticleDOI
Wideband SSFP: alternating repetition time balanced steady state free precession with increased band spacing.
TL;DR: A novel balanced SSFP technique for widening the band spacing in the frequency response is described, called wideband SSFP, which utilizes two alternating repetition times with alternating RF phase, and maintains high SNR and T2/T1 contrast.
