Overview
CT is very sensitive for identifying acute hemorrhage and is considered the gold standard.[1][2]
CT
Noncontrast cranial CT is very sensitive for identifying acute hemorrhage and is considered the gold standard.[1][2]
The following information can be defined by CT scan:
- The size and location of the hematoma
- Ventricular extension of the hematoma
- Presence of edema
- Brain shifts and herniation
| Type of hemorrhage | Radiologic criteria |
|---|---|
| Hyperacute | Hyperdense |
| After one week | Isodense
Ring enhancemen |
| Chronic blood | Hypodense |
| Hemorrhagic transformation of a cerebral infarct | Patchy appearance of the hyperdensity within a larger area of low attenuation
Wedge-shaped abnormality that extends to the cortex. |
Images
The following are images associated with intracerebral haemorrhage.[3]
-
Large hemorrhagic focus in the left cerebral hemisphere that extends to the infratentorial region with a significant mass effect -
Large hemorrhagic focus in the left cerebral hemisphere that extends to the infratentorial region with a significant mass effect -
Multiple descrete bilateral supratentorial intraparenchymal cerebral haemorrhage -
Very large intracerebral haemorrhage on the left extends to involve the ventricles. It exerts marked mass effect -
Hemorrhagic stroke in the left basal ganglia
