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.
Parameters:
(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)
