TL;DR: Imaging normal brain metabolism with hyperpolarized [1–13C]pyruvate and subsequent quantification, have important implications for interpreting pathological cerebral metabolism in future studies.
Journal ArticleDOI

TL;DR: Imaging of hyperpolarized [1-13C]pyruvate metabolism in breast cancer is feasible and demonstrated significant intertumoral and intratumoral metabolic heterogeneity, where lactate labeling correlated with MCT1 expression and hypoxia.
Journal ArticleDOI
The capacity of the TNF family members 4-1BBL, OX40L, CD70, GITRL, CD30L and LIGHT to costimulate human T cells
Johanna Kober,Judith Leitner,Christoph Klauser,Ramona Woitek,Otto Majdic,Johannes Stöckl,Dietmar Herndler-Brandstetter,Beatrix Grubeck-Loebenstein,Birgit M. Reipert,Winfried F. Pickl,Katharina Pfistershammer,Peter Steinberger +11 more
TL;DR: 4‐1BBL, which was found to be the most potent molecule in this group, was able to mediate sustained activation and proliferation of human T cells and it is suggested that these molecules might be functionally distinct from the costimulatory members of this family.
Journal ArticleDOI
Radiomics of computed tomography and magnetic resonance imaging in renal cell carcinoma-a systematic review and meta-analysis.
Stephan Ursprung,Lucian Beer,Lucian Beer,Annemarie Bruining,Ramona Woitek,Ramona Woitek,Grant D. Stewart,Ferdia A. Gallagher,Evis Sala +8 more
TL;DR: Radiomics algorithms show promise for answering clinical questions where subjective interpretation is challenging or not established, however, the generalizability of findings to prospective cohorts needs to be demonstrated in future trials for progression towards clinical translation.
Journal ArticleDOI
The ribs unfolded - a CT visualization algorithm for fast detection of rib fractures: effect on sensitivity and specificity in trauma patients
Helmut Ringl,Mathias Lazar,Michael Töpker,Ramona Woitek,Helmut Prosch,Ulrika Asenbaum,Csilla Balassy,Daniel Toth,Michael Weber,Stefan Hajdu,Grzegorz Soza,Andreas Wimmer,Thomas Mang +12 more
TL;DR: Using CPRs for the detection of rib fractures accelerates the reading of trauma patient chest CTs, while offering an increased overall sensitivity compared to conventional standard MPRs.
