Abstract

We built a low‐cost system for monitoring human skin conductance responses (SCRs) in a clinical magnetic resonance (MR) scanner during functional imaging. The average scanner‐induced conductance noise level was suppressed sufficiently to allow SCR measurements over the full range of SCR amplitudes, and functional image signal‐to‐noise ratio was unaffected by the skin conductance apparatus. The system may be useful for a variety of imaging studies. J. Magn. Reson. Imaging 2001;14:187–193. © 2001 Wiley‐Liss, Inc.

## In a project on the mapping of body surface potentials evoked by implanted spinal cord stimulators and transcutaneous electrostimulators, a simple device was developedfor use in polyclinicalpracticefor easy checking of the function of these stimulators. The device is an electrical stethoscope and
