The volume of an intracerebral hemorrhage can be calculated based on analysis of imaging studies of the brain. This may referred to as the ABC or ABC/2 method since 3 measurements are multiplied.


Goals when examining the scanning cuts:

(1) Identify the largest area of hyperdensity in the scans.

(2) Count the number of cuts containing hemorrhage.



(1) largest diameter of hemorrhage in cm from the cut with the largest area

(2) perpendicular diameter to the axis in #1

(3) number and thickness of cuts containing hemorrhage


volume of hemorrhage in mL =

= 0.5 * (largest diameter) * (perpendicular diameter) * (number of cuts) * (thickness of cut in cm)
