Ultra-low-field Cardiac Cine MRI with Deep Learning

Puntos clave

The proposed approach effectively enhances cardiac imaging quality by reducing noise and artefacts.
With the implementation of deep learning, the analysis of cardiac function at ultra-low-field strengths shows significant promise.
3D cardiac cine MRI at 0.05T demonstrates improved resolution compared to traditional methodologies.
Applying a 4D deep learning framework allows for better restoration of anatomical details and temporal coherence.

Resumen

Motivation: Advance low-cost shielding-free ultra-low-field (ULF) MRI for cardiac imaging by tackling its two fundamental limitations, low spatial resolution and signal-to-noise ratio. Goal(s): To acquire 3D cardiac cine data at 0.05T, and boost 4D image quality with deep learning by leveraging spatiotemporal information available in 3D cardiac cine data. Approach: We implemented 3D bSSFP for 0.05T 3D cardiac cine imaging and developed a 4D recurrent deep learning framework with fully 4D convolutions. Results: Proposed 4D framework effectively suppressed noise, artefacts while restoring anatomical details and temporal coherence in 0.05T 3D cardiac cine data. This approach potentially enables heart function and morphology assessment at 0.05T. Impact: Enhancing image resolution and fidelity for 8-min 0.05T free-breathing 3D cardiac cine imaging using data-driven 4D deep learning approach potentially enables assessment of cardiac function and morphology at 0.05 Tesla.
