Journal ArticleDOI
Diffusion-weighted MR for Differentiation of Breast Lesions at 3.0 T: How Does Selection of Diffusion Protocols Affect Diagnosis?
Wolfgang Bogner,Stephan Gruber,Katja Pinker,Günther Grabner,Andreas Stadlbauer,Michael Weber,Ewald Moser,Thomas H. Helbich,Siegfried Trattnig +8 more
TL;DR: Optimum ADC determination and DW imaging quality at 3.0 T was found with a combined b value protocol of 50 and 850 sec/mm(2), which provided a high accuracy for differentiation of benign and malignant breast tumors.
Journal ArticleDOI
Readout-segmented Echo-planar Imaging Improves the Diagnostic Performance of Diffusion-weighted MR Breast Examinations at 3.0 T
Wolfgang Bogner,Katja Pinker-Domenig,Hubert Bickel,Marek Chmelik,Michael Weber,Thomas H. Helbich,Siegfried Trattnig,Stephan Gruber +7 more
TL;DR: DW imaging based on readout-segmented echo-planar imaging provided significantly higher image quality and lesion conspicuity than single-shot echo-Planar imaging by reducing geometric distortions, image blurring, and artifact level with a clinical high-field-strength MR imager.
Journal ArticleDOI
Treatment Response Assessment in IDH-Mutant Glioma Patients by Noninvasive 3D Functional Spectroscopic Mapping of 2-Hydroxyglutarate
Ovidiu C. Andronesi,Franziska Loebel,Franziska Loebel,Wolfgang Bogner,Małgorzata Marjańska,Matthew G. Vander Heiden,A. John Iafrate,Jorg Dietrich,Tracy T. Batchelor,Elizabeth R. Gerstner,William G. Kaelin,Andrew S. Chi,Bruce R. Rosen,Daniel P. Cahill +13 more
TL;DR: The results indicate that quantitative in vivo 2HG imaging may be used for precision medicine and early response assessment in clinical trials of therapies targeting IDH-mutant gliomas and demonstrate that dynamic measurements of 1HG are feasible by 3D fSM.
Journal ArticleDOI
Assessment of 31P relaxation times in the human calf muscle: A comparison between 3 T and 7 T in vivo†
Wolfgang Bogner,Marek Chmelik,Albrecht Ingo Schmid,Ewald Moser,Siegfried Trattnig,Stephan Gruber +5 more
TL;DR: At 7 T 31P‐MRS in the human calf muscle offers more than twice as much SNR per unit time in reduced measurement time compared to 3 T, allowing shorter measurements at higher field strengths or up to 62% additional signal‐to‐noise ratio (SNR)per unit time.
Journal ArticleDOI
In vivo quantification of intracerebral GABA by single-voxel (1)H-MRS-How reproducible are the results?
Wolfgang Bogner,Staci A. Gruber,Marc Doelken,Andreas Stadlbauer,Oliver Ganslandt,Uwe Boettcher,S. Trattnig,A. Doerfler,Hermann Stefan,Thilo Hammen +9 more
TL;DR: The reproducibility limitations of GABA quantification in vivo are shown and this technique seems to be a precise tool that can detect GABA confidently.
