The Role of Noncontrast Computed Tomography Markers in Predicting the Clinical Outcome of Cerebral Hemorrhage

The Role of Noncontrast Computed Tomography Markers in Predicting the Clinical Outcome of Cerebral Hemorrhage

The goal of this observational study is to To investigate the ability of Noncontrast Computed Tomography to predict clinical prognosis in Intracerebral Hemorrhage.

The main question it aims to answer is:How to judge the prognosis of patients with cerebral hemorrhage by CT image reading at admission.

Inclusion Criteria:

1. Age≥18 years
2. had completed a CT examination within 24 h of disease onset;
3. had a hemorrhage that was located in the brain parenchyma, including the basal ganglia, thalamus,brain lobes, brainstem, and cerebellum.

Exclusion Criteria:

1. had secondary ICH caused by brain trauma,cerebrovascular malformations, aneurysms, and tumors;
2. had ischemic cerebral infarction hemorrhagic transformation;
3. had undergone surgical treatment (e.g.hematoma removal or puncture drainage) before the CT examination;
4. had images of poor quality that could notbe accurately evaluated;
5. had a hematoma withborders that could not be delineated, thus precluding delineation of the region of interest (ROI).
