简要总结
This project is a pilot study which aims at showing the feasibility of free breathing cardiac MRI using GRICS (Generalized Reconstruction by Inversion of Coupled System)software in a clinical environment.
The GRICS technique has been developed by the IADI (Diagnostic, Adaptive and Interventional Imaging)lab, Nancy, France. It enables free breathing MRI thanks to a reconstruction algorithm which provides artefact-free images based on raw MR data and physiological data from external sensors (respiratory belts, ECG.
In this study, we want to acquire free breathing cardiac cine images during a standard cardiac MR exam and compare those data with the breath-hold ones.
