I am an imaging physicist in the Children's Hospital of Michigan specializing in PET/CT and PET/MR. I currently teach the Nuclear Medicine course in the Graduate Program as well as several guest lectures in the Resident and Undergraduate courses run through the department.

I am principally interested in PET/MR research, focused on diagnostic applications.

My current Research Interests include, but are not limited to:

• PET/CT
• SPECT
• Glioblastoma
• Functional MR
• Kinetic modelling
  

Due to the fact that a majority of the students entering the program choose to study therapeutic physics, most of my research involves post-doctoral candidates and research faculty. However, any student interested in PET/CT/MR research can freely contact me about potential projects.

Recent Projects

• "Increased tryptophan uptake on PET has strong independent prognostic value in patients with a previously treated high-grade glioma."
• "Evaluating signal-correlated noise as a control task with language-related gamma activity on electrocorticography.""Evaluating the arcuate fasciculus with combined diffusion-weighted MRI tractography and electrocorticography."
• "Differentiation of glioblastomas from metastatic brain tumors by tryptophan uptake and kinetic analysis: a positron emission tomographic study with magnetic resonance imaging comparison."
• "Language difficulties in children adopted internationally: Neuropsychological and functional neural correlates."
• "GABAA Receptor Imaging With Positron Emission Tomography in the Human Newborn: A Unique Binding Pattern.""
• "The need for clinical quantification of combined PET/MRI data in pediatric epilepsy
• "15O PET Measurement of Blood Flow and Oxygen Consumption in Cold-Activated Human Brown Fat."
• "Tryptophan PET in pretreatment delineation of newly-diagnosed gliomas: MRI and histopathologic correlates."

Dr. Muzik is a medical physicist who was recruited from the University of Michigan in 1993 to assume the role of a senior physicist in the newly opened Children's Hospital of Michigan PET Center. Since then he established himself as an expert in the kinetic analysis of PET data as well as through his work in the development of image analysis software for integrative analysis of pediatric imaging data. Dr. Muzik is also in charge of the microPET/CT core facility at the WSU Medical School.

Dr. Muzik's research interests include the quantitative analysis of oxidative metabolism in Brown Adipose Tissue (BAT) with the objective to establish the relationship between BAT thermogenesis and uptake of FDG, a widely used (but indirect) measure of brown fat metabolism. In addition, Dr. Muzik's research includes the development of methods that allow quantitative integration of multimodality neuroimaging data obtained from PET, MR, fMRI and DTI modalities with special focus on the quantitative assessment of fiber tract connectivity between PET and ECoG-abnormal brain regions in children with epilepsy.
