TL;DR: To compare a new parallel imaging method for multislice proton magnetic resonance spectroscopic imaging (1H‐MRSI), termed (2 + 1)D‐CAIPIRINHA, with two standard PI methods, two standard methods are compared at 7 Tesla.

Coil combination of multichannel MRSI data at 7 T: MUSICAL
Bernhard Strasser,Marek Chmelik,Simon Robinson,Gilbert Hangel,S. Gruber,Siegfried Trattnig,Wolfgang Bogner,Wolfgang Bogner +7 more
TL;DR: This study evaluated a new method of combining multi‐channel 1H MRSI data by direct use of a matching imaging scan as a reference, rather than computing sensitivity maps, and found it to be a fast, robust and simple way to improve the coil combination in 1HMRSI of the human brain at 7 T.
FMRI correlates of apraxia in Parkinson's disease patients OFF medication.

TL;DR: A first investigation on whether functional magnetic resonance imaging (fMRI) may reveal specific brain activation patterns for PD patients with impaired performance in a coin rotation task finds a perirolandic dissociation with precentral overactivation and postcentral underactivation.

How Much Are Clinical fMRI Reports Influenced by Standard Postprocessing Methods? An Investigation of Normalization and Region of Interest Effects in the Medial Temporal Lobe
Roland Beisteiner,N. Klinger,Ilse Höllinger,Jakob Rath,S. Gruber,Thomas Steinkellner,Thomas Foki,A Geissler +7 more
TL;DR: It is concluded that individual ROIs should be defined on nontransformed functional data and that use of more than one metric for activation quantification is beneficial.
Diffusion-weighted imaging of breast tumours at 3 Tesla and 7 Tesla: a comparison
S. Gruber,Lenka Minarikova,Katja Pinker,Olgica Zaric,Marek Chmelik,Bernhard Strasser,Pascal Baltzer,Thomas H. Helbich,Siegfried Trattnig,Wolfgang Bogner +9 more
TL;DR: 7-T DWI of the breast can be performed with 2.4-fold higher spatial resolution than 3-T, without significant differences in SNR if compared to 3 T, according to IRB-approved study.
