T1 relaxation time of mouse spinal cord after systemic adminstration of manganese chloride was first time mwasured dynamically. T1 and R1 values for both white matter and gray matter were determined for various post-MnCl2 injection time point. Fastest manganese uptake interval was calculated to get the best timing for neural stimulation.
