摘要 脑出血患者约占卒中患者总数的9%~27%,虽然比缺血性卒中的患者少,但病死率及致残率高,危害更为严重。在急性脑出血中超过40%的患者会发生血肿扩大,血肿扩大导致患者的转归不良及病死率增高,因此及时诊断并预防血肿扩大对改善脑出血预后、减少死亡率具有重要意义。现目前除了一些经典预测血肿增大的指标外,影像学征象和特征也有重要提示意义,例如CT血管造影(CTA)的"斑点征"、"泄露征"、"九分法"和CT灌注成像(CTP)的动态"斑点征",基线CT平扫(NCCT)上的超急性期血肿扩大速度、"混杂征"及"黑洞征"。 Cerebral hemorrhage accounts for about 9% - 27% of the total number of stroke patients. Although less than ische- mic stroke patients, mortality and morbidity is high, and the harm is more serious. More than 40% of patients present with acute cerebral hemorrhage hematoma enlargement, leading to poor outcome and increased mortality. So timely diagnosis and prevention of hematoma can improve the prognosis of cerebral hemorrhage, reduce mortality. At present, in addition to some of the classic in- dicators of hematoma prediction, imaging findings and features also have important implications, such as CT angiography (CTA), " sign spot ", "leakage sign", nine points" method and CT perfusion imaging (CTP) , Hyperacute hematoma enlargement rate," Bland signs" and "black hole sign"on baseline CT plain scan (NCCT).
