Abstract

Purpose

To visualize flow dynamics of analytes inside porous metallic materials with laser‐detected magnetic resonance imaging (MRI).

Materials and Methods

We examine the flow of nuclear‐polarized water in a porous stainless steel cylinder. Laser‐detected MRI utilizes a sensitive optical atomic magnetometer as the detector. Imaging was performed in a remote‐detection mode: the encoding was conducted in the Earth's magnetic field, and detection is conducted downstream of the encoding location. Conventional MRI (7T) was also performed for comparison.

Results

Laser‐detected MRI clearly showed MR images of water flowing through the sample, whereas conventional MRI provided no image.

Conclusion

We demonstrated the viability of laser‐detected MRI at low‐field for studying porous metallic materials, extending MRI techniques to a new group of systems that is normally not accessible to conventional MRI. J. Magn. Reson. Imaging 2008;28:1299–1302. © 2008 Wiley‐Liss, Inc.
