Imaging signs for prediction of hematoma growth in acute intracerebral hemorrhage / 国际脑血管病杂志

ABSTRACT

Spontaneous intracerebral hemorrhage is the most deadly type of stroke.Its 30-day mortality rate is nearly 40％.More than 30％ of patients with spontaneous intracerebral hemorrhage will have hematoma growth,which lead to poor outcomes.In addition to the classic predictors,some inaging signs also have important implications for identifying hematoma growth,such as swirl sign,blend sign,and black hole sign on nonenhanced CT scans,extravasation sign on contrast-enhanced CT scans,spot sign on CT angiography,leak sign revealed by the modified imaging method,as well as the spot sign on CT peffusion imaging.
