Abstract:
This article summarizes recent developments concerning MRI-based risk assessment of symptomatic intracerebral hemorrhage (sICH) associated with thrombolytic therapy for acute stroke. Special attention is paid to three imaging parameters: cerebral microangiopathy, lesion size on diffusion weighted imaging (DWI), and the role of cerebral microbleeds. Both severe cerebral microangiopathy and increasing lesion size on DWI are now established risk factors for sICH following thrombolysis, while the presence of a single or few microbleeds is not associated with a substantially elevated sICH risk.
Insights
Severe cerebral microangiopathy and large diffusion-weighted imaging (DWI) lesions increase the risk of symptomatic intracerebral hemorrhage (sICH) after thrombolytic therapy for acute stroke. A few cerebral microbleeds do not significantly elevate this risk.
Area of Science:
- Neurology
- Radiology
- Medical Imaging
Context:
- Thrombolytic therapy is crucial for acute stroke treatment.
- Symptomatic intracerebral hemorrhage (sICH) is a serious complication of thrombolysis.
- Accurate risk assessment is needed to optimize patient selection for thrombolysis.
Purpose:
- To summarize recent advancements in MRI-based risk assessment for sICH.
- To evaluate the predictive value of specific imaging parameters for sICH risk.
Summary:
- Severe cerebral microangiopathy and larger lesion volumes on diffusion-weighted imaging (DWI) are established risk factors for sICH post-thrombolysis.
- The presence of a few cerebral microbleeds is not significantly associated with an increased risk of sICH.
- MRI parameters like cerebral microangiopathy and DWI lesion size are key for assessing sICH risk.
Impact:
- Improved patient stratification for thrombolytic therapy in acute stroke.
- Enhanced understanding of MRI's role in predicting treatment complications.
- Potential reduction in adverse events associated with stroke thrombolysis.
