Dr. Joshua Kaggie is a post-doctoral researcher who recently joined the University of Cambridge Radiology Department from the University of Utah. His research interests include the use of sodium and T1rho MRI for detecting cancer and osteoarthritis, ultra-short TE imaging, and the development of radiofrequency coils and arrays.
T1rho and sodium MRI may be early indicators of osteoarthritis through either relaxivity or concentration changes, respectively. We are currently evaluating these techniques in both healthy and diseased subjects to determine whether these will be useful biomarkers for early osteoarthritis detection.
