ct formula for cerebral hemorrhage

Cerebral hemorrhage refers to non-traumatic intracerebral hemorrhage. Symptoms often peak in minutes to hours after onset. The most common site of cerebral hemorrhage is basal ganglia, followed by cerebellum, cerebral lobe and brain stem. The focus of cerebral hemorrhage appears as high-density focus on head CT. After cerebral hemorrhage, the patient can be diagnosed immediately by head CT examination, and the specific value of cerebral hemorrhage volume can be obtained by computer. The amount of cerebral hemorrhage measured by this method is very accurate. If the patient's head CT examination report is missing, or the amount of cerebral hemorrhage at that time is forgotten, the amount of bleeding can be roughly estimated from the head CT film. The estimation method is the length × width × layer/2 of the largest layer of bleeding volume. If the cerebral hemorrhage breaks into the ventricle, the amount of bleeding measured by this method is much smaller than the actual amount.
