Multimodal MEMPRAGE, FLAIR, and R2* Segmentation to Resolve Dura and Vessels from Cortical Gray Matter

Autor: Roberto Viviani, Eberhard D. Pracht, Daniel Brenner, Petra Beschoner, Julia C. Stingl, Tony Stöcker

Publikováno v: Frontiers in Neuroscience, Vol 11 (2017)

While widely in use in automated segmentation approaches for the detection of group differences or of changes associated with continuous predictors in gray matter volume, T1-weighted images are known to represent dura and cortical vessels with signal

Interleaved binomial ksubT/sub-points for water-selective imaging at 7T

Autor: Daniel, Löwen, Eberhard D, Pracht, Rüdiger, Stirnberg, Patrick, Liebig, Tony, Stöcker

Publikováno v: Magnetic resonance in medicineREFERENCES. 88(6)

We present a time-efficient water-selective, parallel transmit RF excitation pulse design for ultra-high field applications.The proposed pulse design method achieves flip angle homogenization at ultra-high fields by employing spatially nonselectivemm

GRAPPA reconstructed wave-CAIPI MP-RAGE at 7 Tesla

Autor: Daniel Brenner, Martin Reuter, Tony Stöcker, Eberhard D. Pracht, Jolanda M. Schwarz

Publikováno v: Magnetic Resonance in Medicine. 80:2427-2438

Purpose The aim of this project was to develop a GRAPPA-based reconstruction for wave-CAIPI data. Wave-CAIPI fully exploits the 3D coil sensitivity variations by combining corkscrew k-space trajectories with CAIPIRINHA sampling. It reduces artifacts
