摘要目的：探讨非增强CT（NCCT）混杂征对脑出血血肿扩大的预测价值。方法：纳入126例脑出血患者进行研究，患者于入院时进行NCCT检查，并在入院后48 h内复查NCCT检查，评估入院时NCCT图像是否存在混杂征，并对比两次NCCT检查的血肿体积。结果：126例脑出血患者中入院NCCT图像上40例出现混杂征，38例血肿扩大患者中30例出现混杂征，混杂征阳性组血肿体积大于阴性组（P＜0.001），混杂征预测血肿扩大的灵敏度、特异度、阳性预测值、阴性预测值分别为78.95%、88.64%、75.00%、90.70%。结论：NCCT混杂征对脑出血血肿扩大有临床预测价值。

Abstract：Objective: To explore the value of nonenhanced CT(NCCT) blend sign in predicting hematoma growth. Methods: Altogether 126 cerebral hemorrhage patients were enrolled in our study. All the patients underwent NCCT scan when they were hospitalized. The follow-up CT scan was preformed within 48 hours after the admission NCCT. It was assessed whether there was blend sign on admission NCCT. The volume of hematoma was compared between two examinations. Results: Blend sign was observed in 40 of 126 patients with intracerebral hemorrhage on admission NCCT scan. Of the 38 patients with hematoma growth, 30 patients had blend sign on admission NCCT scan. The volume of hematoma in the positive blend sign group was greater than that in the negative group. The sensitivity, specificity, positive and negative predictive values of blend sign for predicting hematoma growth were 78.95%, 88.64%, 75.00% and 90.70%. Conclusion: The NCCT blend sign is of clinical value in predicting hematoma enlargement after intracerebral hemorrhage.
