Overview
Other imaging findings in diagnosis of intracerebral hemorrhage may include CT angiography (CTA), CT venography (CTV), MR angiography (MRA), MR venography (MRV), and ctheter angiogram.[1][2]
Other imaging findings
CTA/CTV
- CT angiography (CTA) may identify patients at high risk of intracerebral hemorrhage (ICH) expansion based upon the presence of contrast extravasation within the hematoma.[1][3]
- CTA/CTV are reasonably sensitive at identifying secondary causes of hemorrhage, including:[4]
- 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:[2]
- 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).
Catheter angiogram
A catheter angiogram may be considered if clinical suspicion is high or noninvasive studies are suggestive of an underlying lesion.[5]
Catheter angiography may indicated in following conditions:[6]
- Abnormal calcifications
- Blood in atypical locations (nonhypertensive participants with basal ganglion hematoma)
- Young patients with no obvious cause
