| Summary: | Magnetic resonance imaging (MRI) is arguably the most powerful of all the medical imaging modalities, which has revolutionized medicine and neuroscience. Along with major improvements in resolution and speed over the past few years, recent advances in compressed sensing and simultaneous multi-slice acquisitions have cut the time of MRI scans up to ten-fold, effectively addressing one of the most significant limitations of MRI: slow acquisition. The other main limitation of MRI is its susceptibility to motion. Despite significant efforts and improvements, uncontrolled motion remains as one of the most pressing and persistent limitations of MRI, severely hindering its use in imaging moving organs and moving subjects such as fetuses, newborns, and young children who cannot remain still in the scanner.
