Magnetic resonance imaging of hemorrhagic cerebral infarction.
A comparative study between magnetic resonance (MR) and computed tomography (CT) showed MR to be more sensitive than CT for detecting subacute and chronic hemorrhage into cerebral infarction. The hemorrhage appeared as either high signal on T1 weighted images or low signal on T2 weighted images, depending on the age of the hemorrhage. Cortical hemorrhagic infarction showed a characteristic gyral pattern. Methemoglobin and hemosiderin served as markers of previous hemorrhage into cerebral infarcts.
