Overview
Other imaging findings
Gradient echo (GRE)
- Gradient echo (GRE) is as sensitive as CT for detection of acute blood and are more sensitive for identification of prior hemorrhage.[1][2]
CTA/CTV
- CT angiography (CTA) and contrast-enhanced CT may identify patients at high risk of intracerebral hemorrhage (ICH) expansion based upon the presence of contrast extravasation within the hematoma.[3][4]
- CTA/CTV are reasonably sensitive at identifying secondary causes of hemorrhage, including:[5]
- Arteriovenous malformations (AVM)
- Tumors
- Moyamoya
- Cerebral vein thrombosis
- A CT venogram should be performed if neuroimaging suggest [[cerebral vein thrombosis] (abnormal signal in the cerebral sinuses)
MRA/MRV
- MRA/ MRV are reasonably sensitive at identifying secondary causes of hemorrhage, including:[6]
- Arteriovenous malformations (AVM)
- Tumors
- Moyamoya
- Cerebral vein thrombosis
- An MR venogram should be performed if neuroimaging suggest [[cerebral vein thrombosis] (abnormal signal in the cerebral sinuses).
