Biopsy needle susceptibility artifacts
Mark E. Ladd,Peter Erhart,Jörg F. Debatin,Benjamin J. Romanowski,Peter Boesiger,Graeme C. McKinnon +5 more
TL;DR: Computer simulations of the image distortion resulting from magnetic susceptibility differences between a needle and the surrounding tissue show not only an artifact size that is dependent on needle composition, orientation, and pulse sequence, but also a corresponding shift of the artifact center away from the actual center of the needle.

Single-loop coil concepts for intravascular magnetic resonance imaging.
Harald H. Quick,Mark E. Ladd,Gesine G. Zimmermann-Paul,Peter Erhart,Eugen Hofmann,Gustav K. von Schulthess,Jörg F. Debatin +6 more
TL;DR: The comparison of both catheter approaches in in vitro flow experiments and in an in vivo pig experiment revealed the influence of pulsatile flow on image quality during intravascular imaging with these designs.

Temperature quantification using the proton frequency shift technique: In vitro and in vivo validation in an open 0.5 tesla interventional MR scanner during RF ablation
René M. Botnar,Paul Steiner,Benjamin Dubno,Peter Erhart,Gustav K. von Schulthess,Jörg F. Debatin +5 more
TL;DR: The proton frequency shift (PFS) technique was used to synthesize thermal maps after RF ablation in an open 0.5 T MR system under ex vivo and in vivo conditions using the PFS technique, an accurate and fast imaging method for temperature quantification.

Intravascular MR imaging of atherosclerotic plaque: ex vivo analysis of human femoral arteries with histologic correlation.
Gesine G. Zimmermann,Peter Erhart,J Schneider,G. K. von Schulthess,M Schmidt,Jörg F. Debatin +5 more
TL;DR: Intravascular MR imaging on the basis of the balloon catheter design enables differentiation of wall layers and plaque components.

Active biplanar MR tracking for biopsies in humans
TL;DR: The results of this study prove that the biplanar tracking concept can be applied in a clinical environment and the applicability of biPlanar tracking is further enhanced by integrating an internal signal source.
