MRI scan for hemorrhagic stroke

The above figure shows the changes on the MRI tomogram with intracerebral hemorrhage in the head. brain (hemorrhagic stroke) on the first, third, seventh and fourth days from the onset of clinical symptoms.

In hemorrhages, changes in the intensity of the magnetic resonance signal and the resulting differences in tissue contrast are determined by many biological and technical factors.

Of the first, the state of the hemoglobin molecule associated with the transition of oxyhemoglobin to deoxyhemoglobin (2-4 days), and then into methemoglobin (from 5-7 days) and hemosiderin, which changes the magnetic properties this connection.

Of the technical factors, the strength of the magnetic field of the tomograph and the features of the study modes used are important.

After hemorrhage on T2 images, abnormalities can persist for several years, which is associated with the deposition of hemosiderin in the walls and tissue of the brain.
