Body Imaging at 7T: A Path Toward Clinical Translation by Greg Metzger, Ph.D.; et al. (University of Minnesota Center for Magnetic Resonance Research (CMRR)), Minneapolis, MN, USA. The evolution of ultra-high-field (UHF) magnetic resonance imaging (MRI) at 7 Tesla is gradually unlocking opportunities for high-resolution anatomical and functional imaging of the human torso. Over nearly two decades, progress in radio-frequency (RF) hardware, transmit chain architectures, and electromagnetic field management strategies have addressed many of the challenges associated with transmit B1 (B1+) inhomogeneity and specific absorption rate (SAR) constraints. Key developments include the transition from single-channel to parallel transmit (pTx) systems, the development of multichannel transceiver arrays, and advanced RF shimming and pulse design techniques that balance B1+ efficiency and homogeneity. High-quality images obtained at 7T and 10.5T in the pelvis, abdomen, and chest demonstrate the potential for clinical translation, while ongoing innovations in real-time SAR monitoring, calibration methods, and universal solutions promise to streamline workflows. 7T MRI is poised to transform precision medicine by merging high sensitivity with molecular insights. In this article, the authors review the interplay between technological innovation and anatomy-specific imaging at CMRR, concluding with a roadmap for clinical adoption.
