Low-rank models that exploit the intrinsic redundancy in multidimensional MR signals for image reconstruction from sparse, noisy, and/or corrupted data have been widely used. These models serve as effective constraints for high-dimensional imaging problems that arise in many applications, e.g., dynamic MRI, quantitative MRI, and spectroscopic imaging. This talk will review what low-rank models are, how low-rank structures emerge or can be purposely induced from multidimensional MR data, and how they may be used in image reconstruction. Potential synergy with recent deep learning based reconstruction approaches will also be discussed.

In recent years, deep learning has made significant advancements in MRI reconstruction. However, conventional methods often require full-sampled MRI data, presenting challenges in data acquisition. Consequently, unsupervised learning methods have garnered attention. This discussion delves into various unsupervised deep learning approaches for MRI reconstruction, including unpaired, self-supervised, and zero-shot (untrained) learning. Moreover, we foresee a promising future for unsupervised learning in MRI reconstruction, particularly in collaboration with large-scale foundation models, thereby facilitating further progress in MRI technology.

This lecture will provide a brief overview of the considerations involved in the clinical translation of classical and artificial intelligence approaches to image reconstruction. The systematic evaluation and validation of new reconstruction methods will be discussed in the context of fast imaging methods for acquisition and reconstruction, with an emphasis on prioritizing image quality, minimizing artifacts, and maximizing diagnostic impact. A multidisciplinary, team-based approach with close collaboration between MRI physicists, engineers, data scientists, radiologists, and radiologic technologists is of paramount importance to ensure that new reconstruction methods are integrated seamlessly into the clinical workflow.
