Research: Magnetic Resonance Imaging / Magnetic Resonance Spectroscopy

Dr. Dydak’s research is focused on the development of Magnetic Resonance Spectroscopy (MRS) for the noninvasive in-vivo assessment of biologically important molecules in normal biochemical processes and the disruption of these molecules in human disease and disorders.  A long-term goal of this research is to translate the knowledge gained through the development and application of novel MRS methods into viable clinical diagnostic procedures that aid in disease detection as well as assessment of treatment response. Special emphasis of her work lies on the development of the in vivo detection and quantification of γ-aminobutyric acid (GABA), an inhibitory neurotransmitter, to study manganese-induced parkinsonian neurotoxicity. A second focus lies on the development of whole-liver phosphorous (31P) magnetic resonance spectroscopic imaging of the human liver to improve treatment monitoring in liver cancer. Dr. Dydak holds an adjunct appointment at the Department of Radiology and Imaging Sciences at IU School of Medicine, where part of her research lab is located. MRI/MRS techniques used, optimized or developed in the Dydak lab comprise:

  • Neuroimaging to study occupational manganese neurotoxicity
  • Quantification of in vivo GABA measurements by MRS
  • GABA mapping by MEGA spectroscopic imaging
  • Fast 3D multi-nuclear MRSI (31P MRS) to monitor response to radiation treatment in the human liver
  • High resolution 1H MRS in the rat brain

Using these techniques, Dr. Dydak's group is currently involved in the following collaborative projects:

  • Neuroimaging of Manganese Neurotoxicity in Welders
  • GABA and Glu as marker of disease progression in Parkinson Disease
  • Associations of Brain GABA levels with fine motor skills
  • Brain GABA changes in patients with Essential Tremor 
  • Brain GABA changes in bruxism
  • multi-channel 31P MRSI for the assessment of radiation treatment response in liver cancer

  • HSCI 590 - Molecular Imaging - Part I: Magnetic Resonance Spectroscopy (spring)
  • HSCI 690 – MRI Quality Assurance (Internship)
