How is the ICH volume calculated using the ABC2 formula?

The calculator uses the formula length × width × slice width × number of slices divided by 2, where length and width are measured from the CT scan and slice width is the thickness of each image slice.

Can this tool diagnose the severity of an intracranial hemorrhage?

No, the calculator provides a volume estimate only; clinical severity and mortality assessment require additional scoring systems and professional medical evaluation.

What do the hematoma categories I, II, and III represent in the results?

The tool estimates volume for each ICH scale category based on the input dimensions, helping to categorize the size of the parenchymal hemorrhage observed on the CT scan.

Is the ICH Volume Calculator on Omni Calculator free to use?

Yes, the tool is freely accessible on the Omni Calculator website, though results should always be discussed with a healthcare provider for clinical decision-making.

About this tool

What ICH Volume Calculator does

The ICH Volume Calculator on Omni Calculator estimates the volume of an intracranial hemorrhage using CT scan dimensions. Users input the maximum length, width perpendicular to the length, slice thickness, and number of slices affected to receive an estimated volume for each hematoma category (I, II, III). The tool applies the ABC2 formula (length × width × slice width × number of slices / 2) and includes an explanation of the medical abbreviation and a practical example to guide interpretation. A disclaimer reminds users that results are for informational purposes only and must be confirmed with a healthcare provider. The site also offers a linked ICH score calculator for assessing severity and mortality, providing a broader clinical context within the same platform.
