预测脑出血患者血肿增大的影像学征象

Imaging signs for predicting hematoma enlargement in patients with intracerebral hemorrhage

血肿增大是脑出血后的一种常见有害事件,可导致神经功能恶化和转归不良,早期发现高危患者有助于预防血肿增大并改善患者转归。虽然血肿增大的确切机制尚不清楚,但越来越多的证据表明,多种影像学征象可能与血肿增大相关,例如斑点征、混合征、黑洞征、岛征等。文章主要从影像学角度对血肿增大的相关影像学预测因素进行了综述。

Hematoma enlargement is a common harmful event after cerebral hemorrhage,which can lead to deterioration of neurological function and poor outcome.Early detection of high-risk patients can help prevent hematoma enlargement and improve the outcome of patients.Although the exact mechanism of hematoma enlargement is unclear,more and more evidence shows that many imaging signs may be related to hematoma enlargement,such as dot sign,mixed sign,black hole sign,island sign,etc.This article mainly reviews the relevant imaging prediction factors of hematoma enlargement from the perspective of imaging.
