The given below is the ABC/2 formula which is used to predict the volume of intracranial hemorrhage from CT measurements. This ABC/2 formula for intracerebral hemorrhage volume is used when a patient has an intracranial/intracerebral hemorrhage on CT and a clinician wants a fast and accurate method to estimate its size. Accurate measurements of length and width of the largest area of hemorrhage is required to perform accurate and correct analysis.

Where,

A = Hemorrhage Shape: If Round/Ellipsoid: 2; Otherwise: 3

B = Hemorrhage Length

C = Hemorrhage Width

D = Number of CT Slices

S = CT Slice Thickness

You can also make use of the online calculator which is designed based on the ABC/2 formula for Intracerebral Hemorrhage Volume to make your calculations easier. Just click on the calculator option which is in the top right corner of the page to navigate to the calculator.
