Ultra low field MRI makes its mark

Physicists at the Los Alamos National Laboratory have demonstrated that MRI can be successfully performed using fields in the millitesla range with SQUIDs, and also that magneto-encephalographic images can be produced simultaneously. This advancement has implications for the cost-effectiveness of MRI in the future, replacing the costly 1 to 1.5 Tesla magnets that are currently used.
