Real-time inversion recovery for infarct visualization during MR-guided interventions

Real-time inversion recovery for infarct visualization during MR-guided interventions

Background Real-time MR imaging is appealing for dynamic procedural guidance. Some MRI-guided procedures, such as catheter ablation or myocardial biopsy, may require the interventionist to visualize infarcted tissue in real-time in order to navigate devices relative to the lesion. Methods to interleave late gadolinium enhancement (LGE) images into a real-time imaging stream (1 in 5 frames) have...

Visualization Software for Real-time, Image-guided Therapeutics in Cardiovascular Interventions

This paper introduces RtViewer, a four-dimensional (3D + time) real-time visualization software for guiding cardiovascular interventions that is open source and freely available. RtViewer was designed to be part of a pipeline that can connect it to a magnetic resonance imaging (MRI) scanner, actively tracked catheters, and navigational devices. The architecture and features of RtViewer will be ...

Optimization of inversion time for postmortem short-tau inversion recovery (STIR) MR imaging.

PURPOSE Signal intensity and image contrast differ between postmortem magnetic resonance (PMMR) images and images acquired from the living body. We sought to achieve sufficient fat suppression with short-tau inversion recovery (STIR) PMMR imaging by optimizing inversion time (TI). MATERIAL AND METHODS We subjected 37 deceased adult patients to PMMR imaging at 1.5 tesla 8 to 60 hours after con...

Safety Management for MR-Guided Interventions

Operating room management is a serious and complex task for hospital managers and the common approach is to develop relevant standard operational procedures. From patient' and staff safety perspective operating room management should be wellstudied and hospital should identify and address any potential risks. Implementation of standard validated tools, especially in safety-related area, is the ...
