Heroes of Progress, Pt. 47: Damadian, Lauterbur and Mansfield
Introducing Raymond Damadian, Paul Lauterbur and Sir Peter Mansfield–three scientists who created and refined the magnetic resonance imaging (MRI) machine. Damadian created the world’s first MRI scanner after he realized that cancerous cells would produce different magnetic resonance signals when compared to normal, non-cancerous cells. Prompted by Damadian’s discoveries, Lauterbur developed a way for MRI machines to visualize these cells' signal differences and produce a clear image of inside a patient’s body. Finally, Mansfield created a technique for MRI scans to be conducted in just seconds, rather than hours, and for the image that the scanners produced to be significantly clearer, and therefore more accurate. Each year, hundreds of millions of MRI scans take place. Thanks to their use, untold millions of lives have been extended or saved.
