Is Leukoaraiosis on CT an accurate surrogate marker for the presence of microbleeds in acute stroke patients?

摘要

Microbleeds (MB) detected on gradient echo magnetic resonance images (GRE) are a potential risk factor for intracerebral hemorrhage after thrombolysis or oral anticoagulation. We assessed whether the presence of MB could be predicted from the extent of white matter disease (WMD) on computed tomography (CT).
