Low-field MRI systems, historically seen as underperforming, are gaining renewed interest due to advancements in technology. These systems now enable techniques previously limited to high-field MRI, offering considerable clinical value with improved imaging modalities like 3D SWI at 0.55T. The application of AI and deep learning in image reconstruction and noise reduction enhances image quality and reduces imaging times. Despite inherent limitations in signal-to-noise ratio and spatial resolution, low-field MRI provides unique advantages, especially in reducing susceptibility artifacts near metal implants, making it a valuable tool in clinical diagnostics and MRI-guided interventions.

The supralinear gains of signal-to-noise and contrast-to-noise ratios have been a driving force for ultra-high field MRI. Many exciting projects worldwide have emerged to leverage this gain and boost the spatiotemporal resolution of brain images, gain sensitivity in fMRI and increase the spectral peak separation. In this context, the highest magnetic field used to date in vivo on humans is 11.7T at CEA, Saclay France. This work presents the latest achievements at this unprecedented field strength, including the first images ever acquired in vivo, as well as a few lessons learnt on the way.
