Description
Currently available free-breathing 3D LGE techniques suffer from long imaging time (between 6 and 16 minutes), especially when aiming to provide readouts with submillimetre high isotropic spatial resolution, or require extensive postprocessing, which questions their usefulness in clinical routine.
What is the ideal state/ if the problem is gone? A 3D free-breathing LGE sequence with high isotropic resolution in a short scan time without extensive postprocessing would be more applicable in clinical routine.
Purpose/ Objective
The proposed Compressed SENSE accelerated free-breathing LGE technique enables for the first time high isotropic spatial resolution in an acceptable scan time without the necessity of extensive postprocessing while providing improved depiction of left ventricular hyperenhanced lesions.
Learning Objectives
To close the gap outlined above
1. Learners need to know about: 3D LGE imaging.
2. Learners need to know how to apply: 3D LGE imaging.
