Overview
MRI is better than CT for detection of acute and chronic hemorrhage. Therefore it should be the preferred test for accurate diagnosis of patients with suspected intracerebral hemorrhage.[1]
MRI
MRI is better than CT for detection of acute and chronic hemorrhage. Therefore it should be the preferred test for accurate diagnosis of patients with suspected intracerebral hemorrhage.[1]
- T2 susceptibility-weighted MRI are as sensitive as CT for detection of acute blood and are more sensitive for identification of prior hemorrhage.[1]
- The appearance of Intracerebral hemorrhage on MRI depends on the age of the hematoma and the type of MR sequence (T1-MRI or T2-MRI).
- As the hematoma ages, hemoglobin (Hb) goes through the following stages:[2]
| Stage | Age | Hemoglobin | 1-MRI | 2-MRI |
|---|---|---|---|---|
| Hyperacute | < 24 hours | Intracellular oxy-Hb | Isointense | Very hyperintense |
| Acute | 1-3 days | Intracellular deoxy-Hb | Slightly hypointense | Very hypointense |
| Early subacute | > 3 days | Intracellular met-Hb | Very hyperintense | Very hypointense |
| Late subacute | > 7 days | Extracellular met-Hb | Very hyperintense | Very hypointense |
| Chronic center | > 14 days | Extracellular hemichromes | Isointense | Very hyperintense |
| Chronic rim | > 14 days | Intracellular hemosiderin | Slightly hypointense | Very hypointense |
Microbleeds
Cerebral microbleeds are best visualized on T2* weighted GRE sequences as punctate areas of low signal.[3][4]
