Topical administration (0.5M, 0.75M, 1.0M, and 1.5M MnCl2) and intravitreal injection (1.0M MnCl2) were evaluated and compared for MEMRI on mouse visual system. Our data showed that the signal enhancement was dependent on the concentration of applied MnCl2. Comparing topical administration and intravitreal injection, 1.0M topical administration resulted in significant enhancements in retina, optic nerves, and superior colliculus, which were similar to the results of intravitreal injection.
