Stages of cerebral hemorrhage. As a hematoma ages, hemoglobin changes through several forms oxyhemoglobin, deoxyhemoglobin, and methemoglobin before the RBCs are broken down into ferritin and hemosiderin. The appearance and evaluation of intracranial hemorrhage on MRI primarily depend on the age of the hematoma and on the imaging sequence or parameters (eg, T1 weighting, T2 weighting).
