His innovative work has led to the development of a unique patent that enhances the visualization of nerve activity.

Latest Patents

William M Spees holds a patent for "Imaging nerve function and pathologies using diffusion basis spectrum imaging." This invention addresses how repetitive electrical activity can produce microstructural alterations in myelinated axons. The patent describes methods for non-invasively visualizing these transient microstructural changes through two magnetic-resonance-based approaches: diffusion fMRI and dynamic Tspectroscopy in ex vivo perfused bullfrog sciatic nerves. The non-invasive diffusion fMRI technique, based on standard diffusion tensor imaging (DTI), effectively localizes sites of axonal conduction blockage, which can occur in neurotrauma or other lesion types. The response from diffusion fMRI is graded according to the total number of electrical impulses carried through a specific locus. Additionally, the diffusion basis spectrum imaging (DBSI) method reveals a reversible shift of tissue water into a restricted isotropic diffusion signal component, consistent with sub-myelinic vacuole formation.

Career Highlights

William M Spees is affiliated with Washington University, where he continues to advance research in medical imaging. His work has garnered attention for its potential applications in diagnosing and understanding nerve-related conditions.
