    ABC/2 Formula for Intracerebral Hemorrhage Volume

    Predicts volume of intracranial hemorrhage from CT measurements.


    Measure length and width on the CT slice with the largest area of hemorrhage. NOTE: CT slices are typically measured in mm, not cm.
    When to Use
    Why Use

    A patient has an intracranial/intracerebral hemorrhage on CT and a clinician wants a fast and accurate method to estimate its size.

    Remember to always measure accurately using the length and width of the largest area of hemorrhage.

    Radiologists and non-radiologists alike can estimate ICH size without the need for volumetric 3D analysis from CT or radiology software, which many non-radiologists are unfamiliar with.
