Abstract
We are investigating an application of the biomagnetic measurement to non-invasive diagnosis of spinal cord function. Multichannel superconducting quantum interference device (SQUID) biomagnetometer systems for the measurement of the evoked magnetic field from spinal cords were developed as hospital-use apparatuses. The specific pattern transition of the spinal cord evoked field distribution was clearly observed. The conduction velocity of the cervical spinal cord, which is a significant information for the diagnosis of the dysfunction, was non-invasively estimated from the magnetic measurement.
