Special Issue Information

Dear Colleagues,

Magnetic resonance imaging (MRI) has become an indispensable tool in modern medicine, providing critical anatomical and functional information. The continuous advancements in MR data acquisition and image reconstruction techniques have significantly enhanced the quality, speed, and versatility of MRI, enabling more precise and comprehensive diagnostic capabilities.

Traditional MRI methods, while effective, often face limitations such as long acquisition times and artifacts that can impede accurate diagnosis. Recent innovations in MR technology, including accelerated acquisition methods, novel reconstruction algorithms, and the integration of artificial intelligence, have begun to address these challenges, offering faster imaging and improved image quality.

This Special Issue of Information invites contributions focusing on the latest developments in MR data acquisition and image reconstruction techniques. We welcome both reviews and original research articles that explore innovative approaches to the following topics:

  • Accelerated MRI acquisition methods;
  • Advanced image reconstruction algorithms;
  • Artifact-reduction techniques;
  • AI and machine learning applications in MRI;
  • High-resolution and quantitative imaging;
  • Multimodal and functional imaging enhancements.

Our goal is to showcase cutting-edge research that enhances the robustness, reproducibility, and clinical applicability of MRI. We encourage submissions that aim to translate these technological advancements into routine clinical practice, ultimately improving patient outcomes through more accurate and efficient imaging solutions.

MRF-Mixer is a novel deep learning method for magnetic resonance fingerprinting (MRF) reconstruction, offering 200× faster processing (0.35 s on CPU and 0.3 ms on GPU) and 40% higher accuracy (lower MAE) than dictionary matching. It develops a simulation-driven approach using complex-valued multi-layer perceptrons and convolutional neural networks to efficiently process MRF data, enabling generalization across sequence and acquisition parameters and eliminating the need for extensive in vivo training data. Evaluation on simulated and in vivo data showed that MRF-Mixer outperforms dictionary matching and existing deep learning methods for T1 and T2 mapping. In six-shot simulations, it achieved the highest PSNR (T1: 33.48, T2: 35.9) and SSIM (T1: 0.98, T2: 0.98) and the lowest MAE (T1: 28.8, T2: 4.97) and RMSE (T1: 72.9, T2: 13.67). In vivo results further demonstrate that single-shot reconstructions using MRF-Mixer matched the quality of multi-shot acquisitions, highlighting its potential to reduce scan times. These findings suggest that MRF-Mixer enables faster, more accurate multiparametric tissue mapping, substantially improving quantitative MRI for clinical applications by reducing acquisition time while maintaining imaging quality.

Super-resolution (SR) techniques have shown significant promise in enhancing the resolution of MRI images, which are often limited by hardware constraints and acquisition time. In this study, we introduce an advanced regularization method for MRI super-resolution that integrates spatially adaptive techniques with a robust denoising process to improve image quality. The proposed method excels in preserving high-frequency details while effectively suppressing noise, addressing common limitations of conventional SR approaches. The validation of clinical MRI datasets demonstrates that our approach achieves superior performance compared to traditional algorithms, yielding enhanced image clarity and quantitative improvements in metrics such as the peak signal-to-noise ratio (PSNR) and structural similarity index (SSIM).
