Do you know the formula for calculating the volume of intracranial hematoma?

*It is only for medical professionals to read for reference.
Which one do you generally use? Acute cerebral hemorrhage is a common clinical cerebrovascular disease, the amount of bleeding directly affects the clinical treatment plan, so CT or MRI must measure the amount of bleeding.

Several measurement methods are introduced below for your reference.

1.
[Bleeding layers X layer thickness (cm) X maximum bleeding area area (measured directly by area measurement method, or length diameter X width diameter, remember that the unit is square centimeters)]/2=approximate number of milliliters.

2.
In the case of acute cerebral hemorrhage, when the operation is opened, the amount of bleeding will generally be a little larger than that estimated by CT, because the brain itself is a closed environment after cerebral hemorrhage, and the bleeding itself has a compression and hemostasis effect on the bleeding blood vessels.
When intracranial pressure After it disappears, the bleeding vessel will continue to bleed, which will cause the amount of bleeding in the image to be often less than that of the craniotomy.

Our usual method is to use intracerebral and epidural hematoma hemorrhage (ml) = maximum slice length × width × layer spacing × number of lesion layers × 0.
5 (cubic centimeters) if the shape of the lesion is still regular.
If there are rules, calculate layer by layer, add layer by layer, and get the result.
In this case, it is more accurate, but the workload is larger.

Intracerebral and epidural hematoma bleeding (ml) = the largest slice length of the lesion × width × layer spacing × number of lesion layers × 0.
5 (cubic centimeters), if the layer spacing is 10MM, then the formula can be simplified as the amount of bleeding = the largest layer of the lesion Length × width × number of lesions × 0.
5.

The measurement should be free of edema.

This formula cannot be used for subdural, intraventricular, and subarachnoid hemorrhage.

3.
There are also commonly used methods to calculate CT intracranial hemorrhage, such as: epidural hematoma hemorrhage (ml) = maximum slice length of the lesion × width × layer spacing × number of lesion layers × 0.
5 (cubic centimeters), which is not only time-consuming and labor-intensive! The most important thing is that there are many patients every day, so there is still so much time! My words are based on being responsible for the patient.
Now there is a slightly simpler method: For example: the bleeding volume of the epidural hematoma (ml) = the maximum length of the lesion × width × the number of layers of the lesion and then divide by 2.
result! 4.
Length × width × number of layers/2 (unit: cm; the number of layers is 1CM as one layer).
