Overview
Other imaging findings
- Gradient echo (GRE) and T2 susceptibility-weighted MRI are as sensitive as CT for detection of acute blood and are more sensitive for identification of prior hemorrhage.[1][2]
- Additionally, 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.
