Overview

Other imaging findings in diagnosis of intracerebral hemorrhage may include gradient echo (GRE), CT angiography (CTA), CT venography (CTV), MR angiography (MRA), MR venography (MRV), and actheter angiogram.

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) 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).

Catheter angiogram

A catheter angiogram may be considered if clinical suspicion is high or noninvasive studies are suggestive of an underlying lesion.[7]

Catheter angiography may indicated in following conditions:[8]

  • Abnormal calcifications in patient with SAH or ICH
  • Blood in atypical locations (SAH in patients with headache or nonhypertensive participants with basal ganglion hematoma)
  • Young patients with no obvious cause for ICH
