Magnetic resonance imaging analysis to detect CMB profiles were investigated in 12 cases. The cohort size is also rather small for a genetic association study. Recent advances in MRI protocols, have created ways in which the magnet and the computer that interprets the data, can identify this hemosidrin staining. What to Know About Hemosiderin Staining - WebMD Thus some splenic hemosiderosis is to be expected, and the amount varies with the species (it is most extensive in the horse). 20.
