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.

TL;DR: Results indicate that ultrafast MR imaging can be used for in vivo fetal imaging, especially in assessing cerebral abnormalities, however, MR imaging should be restricted to situations in which sonographic findings are ambiguous or impaired.

Active MR visualization of a vascular guidewire in vivo
Mark E. Ladd,Gesine G. Zimmermann,Harald H. Quick,Jörg F. Debatin,Peter Boesiger,Gustav K. von Schulthess,Graeme C. McKinnon +6 more
TL;DR: The ability to see the curvature of the guidewire over several centimeters significantly eased manipulation into targeted vessels and represents an important advance toward MR‐guided vascular interventions.

Vascular stents as RF antennas for intravascular MR guidance and imaging.
TL;DR: The potential of using the stent endoprothesis as a radiofrequency (RF) receive‐only probe for MR guidance and lesion imaging was investigated and Active stent visualization allows real‐time MR guidance through the vessel tree and monitoring of stent deployment.

Visualization of vascular guidewires using MR tracking
Mark E. Ladd,Gesine G. Zimmermann,Graeme C. McKinnon,Gustav K. von Schulthess,Charles L. Dumoulin,Robert David Darrow,Eugen Hofmann,Jörg F. Debatin +7 more
TL;DR: In this paper, a vascular guidewire was tracked by incorporation of a miniature radiofrequency (RF) receive coil built into its tip, which can be used to track a small device and simultaneously track multiple devices.
