Journal ArticleDOI
Aggregated neutrophil extracellular traps limit inflammation by degrading cytokines and chemokines
Christine Schauer,Christina Janko,Luis E. Muñoz,Yi Zhao,Deborah Kienhöfer,Benjamin Frey,Michael Lell,Bernhard Manger,Jürgen Rech,Elisabeth Naschberger,Rikard Holmdahl,Veit Krenn,Thomas Harrer,Ivica Jeremic,Rostyslav Bilyy,Georg Schett,Markus H. Hoffmann,Martin Herrmann +17 more
TL;DR: It is reported that neutrophils recruited to sites of inflammation undergo oxidative burst and form neutrophil extracellular traps (NETs), and aggregated NETs promote the resolution of neutrophilic inflammation by degrading cytokines and chemokines and disrupting neutrophIL recruitment and activation.
Journal ArticleDOI
Coronary computed tomography angiography with a consistent dose below 1 mSv using prospectively electrocardiogram-triggered high-pitch spiral acquisition
Stephan Achenbach,Mohamed Marwan,Dieter Ropers,Tiziano Schepis,Tobias Pflederer,Katharina Anders,Axel Kuettner,Werner G. Daniel,Michael Uder,Michael Lell +9 more
TL;DR: In non-obese patients with a low and stable heart rate, prospectively ECG-triggered high-pitch spiral coronary CTA provides excellent image quality at a consistent dose below 1.0 mSv.
Journal ArticleDOI
Normalized metal artifact reduction (NMAR) in computed tomography
TL;DR: In this paper, a generalized normalization technique for MAR is proposed, which can reduce metal artifacts to a minimum, even close to metal regions, even for patients with dental fillings, which cause most severe artifacts.
Journal ArticleDOI
High-pitch spiral acquisition: a new scan mode for coronary CT angiography.
Stephan Achenbach,Mohamed Marwan,Tiziano Schepis,Tobias Pflederer,Herbert Bruder,Thomas Allmendinger,Martin Petersilka,Katharina Anders,Michael Lell,Axel Kuettner,Dieter Ropers,Werner G. Daniel,Thomas Flohr,Thomas Flohr +13 more
TL;DR: A new scan mode that uses a very high-pitch spiral acquisition, "Flash Spiral," which has been developed specifically for low-dose imaging with dual-source CT, which allowed artifact-free visualization of the coronary arteries with a radiation exposure of 1.7 mSv for a 12-cm scan range at 120 kVp tube voltage.
Journal ArticleDOI
Dose reduction in computed tomography by attenuation-based on-line modulation of tube current: evaluation of six anatomical regions.
TL;DR: The dose in computed tomography should be reduced substantially by technical measures without sacrificing image quality, and attenuation-based on-line modulation of tube current is an efficient and practical means for this.
