My work focuses on assessment of normal and diseased tissue microstructure and the resultant modulation of tissue metabolism using medical imaging technologies. A great deal of my research involves MRI and in vivo nuclear magnetic resonance (NMR) spectroscopy. However, more recently I have focused on applications of multimodal techniques, or the fusion of MRI with EEG, EMG, ultrasound and other imaging methods. Overall I am interested in developing more comprehensive and diagnostically useful disease imaging protocols for evaluation of anatomic, metabolic and functional characteristics of healthy and abnormal tissues.

Weber AM, Soreni N, Noseworthy MD. (2014)

A Preliminary study on the effects of acute ethanol ingestion on default mode network and temporal fractal properties of the brain


This paper was key in showing how the brain temporal complexity can decrease with intoxication

Liver Functional MRI analysis using a latent variables approach

J. CHEMOMETRICS 26:170-179

Paper won an international award. Because of the dual input function nature of the liver an appropriate model was difficult to elucidate. The multivariate approach was successful as we didn’t have to rely on an a priori model

Dr. Noseworthy received a M.Sc. from the University of Guelph for work in the evaluation of anaesthetic hepatotoxicity using nuclear magnetic resonance imaging (MRI) and in vivo 31P-NMR. Obtained a PhD from University of Guelph (1997) specializing in applications of MRI/NMR, biochemical assays and electron paramagnetic resonance (EPR) methods to assess free radical induced brain damage. From 1997-1999 was a postdoctoral fellow in Imaging Physics, Sunnybrook Health Sciences Centre working on the evaluation of tissue microvasculature through development of correlative MRI and energy dispersive X-ray microanalysis (EDXS). From January 2000 to August 2003 worked as a MRI physicist at The Hospital for Sick Children, Toronto, and Assistant Professor in Medical Biophysics and Medical Imaging, University of Toronto. Moved to St. Joseph’s Healthcare and Brain-Body Institute, McMaster University in August 2003. Following 3 years as an Assistant Professor in Radiology and Medical Physics at McMaster University, Dr. Noseworthy attained a tenure-track position in Electrical & Computer Engineering at McMaster University, where he currently resides as a full professor. His research interests include the assessment of tissue microstructure and metabolism using magnetic resonance imaging (MRI) and multinuclear in vivo nuclear magnetic resonance (NMR) spectroscopic techniques, and the application of complex systems mathematics and machine learning to medical image analysis. Dr. Noseworthy is a member of the Professional Engineers of Ontario (PEO), Institute of Electrical and Electronics Engineers (IEEE), International Society for Magnetic Resonance in Medicine (ISMRM) and European Society for Magnetic Resonance in Medicine and Biology (ESMRMB).
