This study explored the use of high-resolution
quantitative susceptibility mapping-based MRI microscopy
for studying the highly stratified layers ex vivo rat
retina at a spatial resolution of 23 x 23 x 57
m

.
Comparing to magnitude with weak contrast, both gradient
echo phase and magnetic susceptibility shows remarkable
contrast between different layers. These layered
structures from phase and susceptibility is in good
agreement with H&E staining using histology.
