An End-to-End Deep Learning Method for Reconstructing SMS-PI Accelerated Musculoskeletal MRI

Puntos clave

Results show improved reconstruction of MSK MRI scans at 8-fold and 12-fold accelerations, enhancing diagnostic speed and accuracy.
The deep learning method integrates simultaneous multislice and parallel imaging techniques for accelerated image reconstruction.
Proposed techniques achieve better generalizability across various planes, contrasts, and MSK regions, broadening their clinical applicability.
Preliminary findings suggest potential for increased efficiency in MSK MRI, reducing time to diagnosis while maintaining image quality.

Resumen

Motivation: Deep learning (DL) image reconstruction techniques are often utilized in knee MRI with 6-fold acceleration. However, applying these techniques to all musculoskeletal (MSK) MRI and achieving higher acceleration remains a challenge. Goal(s): Develop a dedicated DL image reconstruction method that combines simultaneous multislice (SMS) and parallel imaging (PI) acceleration for MSK MRI. Approach: DL approach combining slice separation and the reconstruction of image data from k-space for SMS-PI-accelerated MSK MRI. It features adjustable denoising strength and enhanced super-resolution image quality. Results: Proposed methods demonstrate improved reconstruction of MSK MRI scans at 8-fold and 12-fold accelerations compared to previous approaches, showing greater overall generalizability. Impact: Proposed methods facilitate the reconstruction of 8-fold accelerated 2D-TSE-MR images across various planes, contrasts, and MSK regions. Preliminary results indicate the feasibility of DL reconstruction at 12-fold acceleration, potentially allowing for significant speed-ups compared to the slower standard of care.
