Patient-friendly MRI scans

New patient populations can undergo magnetic resonance imaging thanks to NSF-funded mathematics research.

Faster MRIs are reducing patient costs for the imaging technique.

In 2017, the U.S. Food and Drug Administration (FDA) approved two new magnetic resonance imaging (MRI) devices that scan between eight and 16 times faster than conventional methods. Cardiac scans now take just 25 seconds and do not require patients to hold their breath. The FDA approval makes MRIs available to patient populations previously ineligible for some scans, such as those with irregular heartbeats, those with dementia and children.

The devices, now commercially available from Siemens (CS Cardiac Sine) and General Electric (Hypersense), rely on compressed sensing, a breakthrough technique developed 10 years ago by NSF-supported mathematicians. Faster MRI scans will give more patients access to the imaging technology at a lower cost per patient.
