Journal ArticleDOI
Automatic, three-segment, MR-based attenuation correction for whole-body PET/MR data.
Volkmar Schulz,Volkmar Schulz,I. Torres-Espallardo,I. Torres-Espallardo,Steffen Renisch,Zhiqiang Hu,Navdeep Ojha,Peter Börnert,Michael Perkuhn,Michael Perkuhn,Thoralf Niendorf,Thoralf Niendorf,Wolfgang Schäfer,H. Brockmann,Thomas Krohn,A. Buhl,Rolf W. Günther,Felix M. Mottaghy,Gabriele A. Krombach +18 more
TL;DR: A fully automated approach that uses a dedicated T1-weighted MR sequence in combination with a customized image processing technique to derive attenuation maps for whole-body PET and offers similar correction accuracy as offered by segmented CT.
Journal ArticleDOI
High-resolution transthoracic real-time three-dimensional echocardiography: quantitation of cardiac volumes and function using semi-automatic border detection and comparison with cardiac magnetic resonance imaging.
Harald P. Kühl,Marcus Schreckenberg,Dierk Rulands,M. Katoh,Wolfgang Schäfer,Georg Schummers,Arno Bücker,Peter Hanrath,Andreas Franke +8 more
TL;DR: The RT-3DE, in combination with a semi-automatic contour tracing algorithm, allows accurate determination of cardiac volumes and function compared with both manual tracing and CMRI and high repeatability suggests applicability of the method for the serial follow-up of patients with cardiac disease.
Journal ArticleDOI
Imaging-based target volume reduction in chemoradiotherapy for locally advanced non-small-cell lung cancer (PET-Plan): a multicentre, open-label, randomised, controlled trial.

TL;DR: 18F-FDG PET-based planning could potentially improve local control and does not seem to increase toxicity in patients with chemoradiotherapy-treated locally advanced non-small-cell lung cancer.
Journal ArticleDOI
Dose-escalation using intensity-modulated radiotherapy for prostate cancer--evaluation of the dose distribution with and without 18F-choline PET-CT detected simultaneous integrated boost.
Michael Pinkawa,Charbel Attieh,Marc D. Piroth,Richard Holy,Sandra Nussen,Jens Klotz,Robert Hawickhorst,Wolfgang Schäfer,Michael J. Eble +8 more
TL;DR: The therapeutic ratio can be improved by a considerable dose escalation to the macroscopic tumour, but only minor EUD changes to the bladder and rectum.
Proceedings ArticleDOI
MR-based attenuation correction for a whole-body sequential PET/MR system
Zhiqiang Hu,Navdeep Ojha,Steffen Renisch,Volkmar Schulz,I. Torres,A. Buhl,Debashish Pal,G. Muswick,J. Penatzer,T. Guo,P. Bonert,Chi-Hua Tung,J. Kaste,Michael A. Morich,T. Havens,Piotr Maniawski,Wolfgang Schäfer,Rolf W. Günther,Gabriele A. Krombach,Ling Shao +19 more
TL;DR: The algorithm seems promising from preliminary patient data evaluation, from both qualitative PET image quality and quantification accuracy, and while the 3-segment MRAC resembles the results from short PET transmission scans, future work will be to implement and validate segmentation of more tissue classes, such as cortical bone.
