Noncontrast computed tomography signs predict early hematoma expansion in intracerebral hemorrhage / 中华神经科杂志

Intracerebral hemorrhage (ICH) is a fatal stroke with high morbidity and mortality.Nearly 1/3 patients with ICH suffer from hematoma expansion (HE),which is directly related to the prognosis.Therefore,the early prediction of HE has important guiding significance for the therapeutic intervention.At present,more and more imaging signs have been found to predict HE,such as CTA points,CTA leakage signs,and CT perfusion dynamic signs.However,non-enhanced CT (NCCT) is widely used as a gold standard for the diagnosis of ICH.Recently,several signs of NCCT have been found,including swirling sign,blend sign,black hole sign,hypodensities in hematoma,island sign and satellite sign.
