Mustafa Çavuşoğlu, Benjamin Emanuel Dietrich, David Otto Brunner, Markus Weiger, Klaas Paul Pruessmann
The accuracy and precision of the parallel RF excitations are highly dependent on the spatial and temporal fidelity of the magnetic fields involved in spin excitation. The consistency between the nominal and effective fields is typically limited by the imperfections of the employed hardware existing both in the gradient system and the RF chain. In this work, we experimentally presented highly impr...... hiện toàn bộ

Assessment of MR imaging during one-lung flooding in a large animal model
Magnetic Resonance Materials in Physics, Biology and Medicine - Tập 32 - Trang 581-590 - 2019
Frank Wolfram, Daniel Güllmar, Joachim Böttcher, Harald Schubert, Sabine Bischoff, Jürgen R. Reichenbach, Thomas Günther Lesser
Magnetic resonance imaging (MRI) of the lung remains challenging due to the low tissue density, susceptibility artefacts, unfavourable relaxation times and motion. Previously, we demonstrated in vivo that one-lung flooding (OLF) with saline is a viable and safe approach. This study investigates the feasibility of OLF in an MRI environment and evaluates the flooding process on MR images. OLF of the...... hiện toàn bộ
DQF-MT MRI of connective tissues: application to tendon and muscle
Magnetic Resonance Materials in Physics, Biology and Medicine - Tập 26 - Trang 203-214 - 2012
Slawomir Kusmia, Uzi Eliav, Gil Navon, Geneviève Guillot
The sequence combining DQF (double quantum filtering) with magnetisation transfer (DQF-MT) was tested as an alternative to the DQF sequence for characterising tendon and muscle by MR imaging. DQF-MT images of tendon–muscle phantoms were obtained at 4.7 T using ultra-short time to echo (UTE) methods in order to alleviate the loss of SNR due to the short T2 of the tissues. Two different sampling sch...... hiện toàn bộ
Three-dimensional in vivo magnetic resonance microscopy of beech (Fagus sylvatica L.) wood
Magnetic Resonance Materials in Physics, Biology and Medicine - Tập 18 - Trang 171-174 - 2005
M. Merela, P. Oven, A. Sepe, I. Serša
Spatial structure and water distribution in branch tissues after mechanical injury were investigated in vivo by three-dimensional (3D) magnetic resonance (MR) microscopy. On a beech tree (Fagus sylvatica L.), transplanted in a portable pot, a branch was topped and then MR imaged. High-resolution 3D MR images revealed structures which could not be identified by conventional MR images or by light mi...... hiện toàn bộ
1H MR spectroscopic imaging with short and long echo time to discriminate glycine in glial tumours
Magnetic Resonance Materials in Physics, Biology and Medicine - Tập 22 - Trang 33-41 - 2008
Elke Hattingen, Heinrich Lanfermann, Johanna Quick, Kea Franz, Friedhelm E. Zanella, Ulrich Pilatus
To investigate glycine (Gly) concentrations in low- and high-grade gliomas based on 1H MR spectroscopic imaging (MRSI) with short and long echo time (TE). Myoinositol (MI) and Gly appear at the same resonance frequency of 3.56 ppm, but due to strong coupling the MI signal dephases more rapidly. Therefore, their contribution to the 3.56 ppm signal should be distinguishable comparing MRSI data acqui...... hiện toàn bộ
