AI-Enhanced Super-Resolution for Metabolite MRI Imaging

Key Points

The proposed model significantly enhanced MRSI resolution, achieving improved image quality measures compared to traditional methods.
Performance metrics, including PSNR and SSIM, showed substantial advancements over spline and nearest-neighbor techniques at a significance level of p<.01.
Synthetic metabolic maps were created using anatomical images from a cohort of 350 patients, ensuring a robust training dataset.
Implementing this enhanced super-resolution method can provide clinicians with detailed neurological assessments based on metabolite imagery.

Abstract

Motivation: Metabolite images from Magnetic Resonance Spectroscopic Imaging (MRSI) suffer from lower quality and reduced detail due to larger voxel sizes compared to anatomical MRI. Goal(s): To improve the visual quality of MRSI by using a deep learning-based super-resolution approach to enhance spatial resolution. Approach: Synthetic metabolic maps were generated using anatomical images from 350 patients. Our CNN-transformer model was trained on 70% of the dataset and tested on the remaining 30%, with performance compared to spline and nearest-neighbor methods. Results: Our model significantly upscaled MRSI resolution to 128×128, achieving significantly higher PSNR, SSIM, and LPIPS scores than spline and nearest-neighbor (p<.01). Impact: This improved SR approach significantly enhances metabolite map quality, offering clinicians a valuable tool for detailed neurological assessment.
