Two channel passive visualization of a nitinol guidewire with iron markers

چکیده
Background MRI-guidance for cardiovascular catheterization is appealing to reduce ionizing radiation exposure and to enable novel procedures. “Active” guidewire-antennas for MRI-guided procedures are often designed such that the tip and shaft have distinct signals [1] to improve navigation and to make it obvious when the tip moves out of plane. Here we present a method to isolate the signal from iron markers, and produce a two channel color overlay for visualizing the shaft and tip of a nitinol guidewire.

Segmented nitinol guidewires with stiffness-matched connectors for cardiovascular magnetic resonance catheterization: preserved mechanical performance and freedom from heating
BACKGROUND Conventional guidewires are not suitable for use during cardiovascular magnetic resonance (CMR) catheterization. They employ metallic shafts for mechanical performance, but which are conductors subject to radiofrequency (RF) induced heating. To date, non-metallic CMR guidewire designs have provided inadequate mechanical support, trackability, and torquability. We propose a metallic g...
متن کاملActive Visualization of MR-Compatible Guidewires
Introduction: Safety concerns exist regarding the use of conventional guidewires in an MR scanner. Recently, an MR-compatible guidewire design has been evaluated that consists of a non-resonant length of nitinol (100mm) attached to a long non-conducting segment made of a glass-fiber reinforced plastic [1, 2]. The guidewire is doped with iron powder to enable passive visualization of the device....
متن کاملPositive contrast spiral imaging of a nitinol guidewire
Background The clinical translation of MRI-guided cardiovascular catheterization has been limited by the unavailability of devices that are both visible and safe under MRI. In particular, rigid metallic guidewires are essential for most catheterization procedures and are at risk of heating during MR imaging [1]. Here we present an MRI method that simultaneously improves the visualization of com...
متن کاملMagnetic resonance--guided coronary artery stent placement in a swine model.
BACKGROUND Magnetic resonance (MR)--guided coronary artery stent placement is a challenging vascular intervention because of the small size of the coronary arteries combined with incessant motion during the respiratory and cardiac cycles. These obstacles necessitate higher temporal and higher spatial resolution real-time MR imaging techniques when compared with interventional peripheral MR angi...
متن کاملPositive contrast spiral imaging for visualization of commercial nitinol guidewires with reduced heating
BACKGROUND CMR-guidance has the potential to improve tissue visualization during cardiovascular catheterization procedures and to reduce ionizing radiation exposure, but a lack of commercially available CMR guidewires limits widespread adoption. Standard metallic guidewires are considered to be unsafe in CMR due to risks of RF-induced heating. Here, we propose the use of RF-efficient gradient e...
