18F-FDG PET/CT Identifies Patients at Risk for Future Vascular Events in an Otherwise Asymptomatic Cohort with Neoplastic Disease
Axel Rominger,Tobias Saam,Sarah Wolpers,Clemens C. Cyran,Michael Schmidt,Stefan Foerster,Konstantin Nikolaou,Maximilian F. Reiser,Peter Bartenstein,Marcus Hacker +9 more
TL;DR: Increased 18F-FDG uptake in major arteries emerged as the strongest predictor of a subsequent vascular event in a large cohort of cancer patients, although mean TBR correlated only with age, the male sex, and hypertension.
Journal ArticleDOI
Prevalence of nonstenosing, complicated atherosclerotic plaques in cryptogenic stroke.
Tobias Freilinger,Andreas Schindler,Caroline Schmidt,Jochen M. Grimm,Clemens C. Cyran,Florian Schwarz,Fabian Bamberg,Jennifer Linn,Maximilian F. Reiser,Chun Yuan,Konstantin Nikolaou,Martin Dichgans,Tobias Saam +12 more
TL;DR: This pilot study suggests that arterio-arterial embolism from complicated, nonstenosing carotid atherosclerotic plaques may play a role in a subgroup of patients previously diagnosed with cryptogenic stroke.
Journal ArticleDOI
Microbubbles as a scattering contrast agent for grating-based x-ray dark-field imaging.
Astrid Velroyen,Martin Bech,Martin Bech,Andreas Malecki,Arne Tapfer,Andre Yaroshenko,Michael Ingrisch,Clemens C. Cyran,Sigrid Auweter,Konstantin Nikolaou,Maximilian F. Reiser,Franz Pfeiffer +11 more
TL;DR: It is shown that ultrasound contrast agents based on microbubbles can be used to produce strongly enhanced dark-field contrast, with superior contrast-to-noise ratio compared to the attenuation signal, and that the relative contrast gain even increases when the pixel size is increased from tenths of microns to clinically compatible detector resolutions.
Journal ArticleDOI
Improved Detection of Transosseous Meningiomas Using 68Ga-DOTATATE PET/CT Compared with Contrast-Enhanced MRI.
Wolfgang G. Kunz,Lisa M Jungblut,Philipp M. Kazmierczak,Franziska Vettermann,Andreas Bollenbacher,Jörg C. Tonn,Christian Schichor,Axel Rominger,Nathalie L. Albert,Peter Bartenstein,Maximilian F. Reiser,Clemens C. Cyran +11 more
TL;DR: 68Ga-DOTATATE PET/CT enables improved detection of the transosseous extension of intracranial meningiomas compared with CE-MRI.
Journal ArticleDOI
Complicated Carotid Artery Plaques as a Cause of Cryptogenic Stroke
Anna Kopczak,Andreas Schindler,Anna Bayer-Karpinska,Mia L. Koch,Dominik Sepp,MA Julia Zeller,Christoph Strecker,Johann-Martin Hempel,Chun Yuan,Rainer Malik,Frank A. Wollenweber,Tobias Boeckh-Behrens,Clemens C. Cyran,Andreas Helck,Andreas Harloff,Ulf Ziemann,Sven Poli,Holger Poppert,Martin Dichgans,Martin Dichgans,Tobias Saam +20 more
TL;DR: Findings substantiate the role of complicated nonstenosing carotid artery plaques (CAPs) in cryptogenic stroke as an under-recognized cause of stroke.
