Journal ArticleDOI
MR imaging in acute stroke: diffusion-weighted and perfusion imaging parameters for predicting infarct size.
Hans-Jörg Wittsack,Afra Ritzl,Gereon R. Fink,Frank Wenserski,Mario Siebler,Rüdiger J. Seitz,Ulrich Mödder,Hans-Joachim Freund +7 more
TL;DR: Diffusion- Weighted imaging helped to predict the size of the lesion on T2-weighted images obtained after about 8 days in patients with a symptom onset of more than 4 hours, while perfusion imaging provided important additional information about brain tissue with impaired perfusion.
Journal ArticleDOI
Recovery from stroke: current concepts and future perspectives
TL;DR: It is demonstrated that the combination of neuroimaging and neurostimulation techniques allows a better understanding of how brain plasticity can be modulated to promote the reorganization of neural networks.
Journal ArticleDOI
Cerebral Glucose Metabolism as a Predictor of Recovery From Aphasia in Ischemic Stroke
TL;DR: The results emphasize not only the application of PET activation studies in the prediction of a tissue's potential reserve capacity but also the importance of left hemisphere integrity in the recovery of functional language.
Journal ArticleDOI
Synchronization tomography: a method for three-dimensional localization of phase synchronized neuronal populations in the human brain using magnetoencephalography.
Peter A. Tass,Thomas Fieseler,Jürgen Dammers,Kevin Dolan,Patricia Morosan,Milan Majtanik,F. Boers,A. Muren,Karl Zilles,Gereon R. Fink +9 more
TL;DR: A noninvasive technique is presented which allows the anatomical localization of phase synchronized neuronal populations in the human brain with magnetoencephalography and studies phase synchronization between the reconstructed current source density (CSD) of different brain areas as well as between the CSD and muscular activity.
Journal ArticleDOI
Comparison of 18F-FET PET and Perfusion-Weighted MR Imaging: A PET/MR Imaging Hybrid Study in Patients with Brain Tumors
Christian Filss,Norbert Galldiks,Norbert Galldiks,Gabriele Stoffels,Michael Sabel,Hans Jörg Wittsack,Bernd Turowski,Gerald Antoch,Ke Zhang,Gereon R. Fink,Gereon R. Fink,Heinz H. Coenen,Nadim Joni Shah,Nadim Joni Shah,Hans Herzog,Karl-Josef Langen,Karl-Josef Langen +16 more
TL;DR: The data show that metabolically active tumor tissue of gliomas as depicted by amino acid PET is not reflected by rCBV as measured with PWI, and in patients with cerebral glioma, tumor imaging with 18F-FET PET and r CBV yields different information.
