Computed tomography angiography-based analysis of high-risk intracerebral haemorrhage patients by employing a mathematical model.

BACKGROUND: Haemorrhagic stroke accounts for approximately 31.52% of all stroke cases, and the most common origin is hypertension. However, little is known about the method to identify high-risk populations of hypertensive intracerebral haemorrhage. RESULTS: The results showed that the angle between the middle cerebral artery and the internal carotid artery (AMIC), the distance between the beginning of the median artery and superior trunk (DMS), and the density (CT value) of the lenticulostriate artery (CTL) were statistically significant enough to cause intracerebral haemorrhage. In addition, we chose these three potential features for the ensemble learning classification model. Our developed ensemble-learning method outperforms not only previous work but also three other classic classification methods based on accuracy measurements. CONCLUSIONS: The developed mathematical model in the present study is efficient in predicting the probability of intracerebral haemorrhage.
