Juan Touya, M.D.

Juan Touya: Juan and his brother Eduardo were the two nuclear medicine physician/scientists key to the developments in Uruguay (Montevideo). Both were active in the Latin American Nuclear Medicine Society before Juan came to the USA to work with Bennett at UCLA. He joined the Vanderbilt faculty in 1976 and  was particularly interested in quantitative analysis of renal differential renal function using kinetic modeling tools.  He tested different methods of measuring GFR in adults and children. He also studied the effects of posture on liver and lung imaging.  and respiratory functional imaging. He also had previous extensive experience with the use of In-113m transferrin, as an alternative to marrow imaging with Fe-59/52.
