AREAS OF SPECIAL INTEREST

Dr. Johnson uses magnetic resonance imaging (MRI) to study the mechanics of tissues in the body and how they can be used to understand the structure, function, and health of various organs, with a specific focus on the human brain. In particular, Dr. Johnson uses the magnetic resonance elastography (MRE) technique, which noninvasively probes tissue viscoelasticity through the imaging of shear waves generated in the body. His research includes the development of high-resolution MRE imaging protocols through MRI pulse sequence design, image reconstruction schemes for accelerated MRE, and incorporation of advanced tissue models such as anisotropy and poroelasticity. Dr. Johnson explores using the MRE technique for a variety of applications in neuroscience, neurology, and neurosurgery, such as better understanding the structure-function relationship of the hippocampus and evaluating meningiomas prior to surgical resection.
