3D Image Enhancement for High-Resolution ky-kz Accelerated 3D LGE CMR

Motivation: Prolonged scan times in high-resolution 3D late gadolinium enhancement (LGE) cardiovascular magnetic resonance (CMR) imaging hinders the full potential in clinical applications. Goal(s): The primary goal of this study was to develop and evaluate a 3D enhanced-resolution for 2D (ky-kz) accelerated 3D LGE imaging. Approach: A 3D generative adversarial network was implemented to enhance the spatial resolution of 2D-accelerated 3D LGE images. Results: The proposed method at 6-fold acceleration (3-fold in ky and 2-fold in kz) maintained intricate scar details and improved image quality. Impact: The improvement in acquisition speed by 2D acceleration may benefit patients presenting with heavy respiratory motion and may be less sensitive to contrast washout.
