High field vs low field mri

WebScientists developed a high-performance, low magnetic-field MRI system that improves image quality of the lungs and other internal body structures. The technology could be used for image-guided procedures and other new clinical applications in the future. The study may lead to new clinical uses for MRI. Mark Kostich / E+ via Getty Images.
