CTA“斑点征”有效预测急性脑出血血肿扩大及临床预后，目前采用斑点征标准，即符合以下四点：①在颅内血肿的对比剂外渗处，出现≥1个增强斑点样病灶；②周围血肿与其密度相比，对比衰减≥120 HU；③在颅内血肿周围，存在相邻的不连续的正常或异常的血管走行；④斑点征存在于颅内血肿范围内。斑点征与脑出血患者3个月病死率和3个月不良临床结局（改良MRS评分）均有很强的相关性，SSSc与血肿扩大及不良预后具有明显的相关性，通过斑点征而形成的九分法可以为临床应用提供方便，并有效区分血肿再扩大的高危病人。

For CTA "spot sign" effective prediction of hematoma enlargement and clinical prognosis of acute cerebral hemorrhage,currently using the spot sign that is consistent with the standard following as four points:1)the contrast agent extravasation at the intracranial hematoma,appear more than 1 enhanced spots like lesions;2)compared with around hematoma density,attenuation is 120HU and more than it;3)in surrounding intracranial hematoma there are adjacent discontinuous normal or abnormal blood vessel shape;4)the spot sign exists in the range of intracranial hematoma. The spot sign is strongly related to 3 month-mortality in patients with cerebral hemorrhage and 3 months-adverse clinical outcome (modified MRS scale),SSSc has obvious relevance to hematoma enlargement and worse prognosis,the nine division method formed by the spot sign can provide convenience for clinical application,and effectively distinguish from the patients at high risk of the hematoma enlargement.
