ICH Volume (ABC/2)
ICH volume by ABC/2 (Kothari 1996): the ellipsoid estimate of intracerebral-hemorrhage volume in mL from three CT dimensions.

Example
- A: greatest diameter
- 5
- B: diameter perpendicular to A
- 4
- C: number of slices x slice thickness
- 3
Result: ICH volume 30 mL by ABC/2 -- meets the ICH-score >= 30 mL threshold (+1 point).
The tool opens with these values already filled in. Replace them with your own.
What the result means
- Threshold
- >= 30 mL is the volume the ICH Score (Hemphill 2001) counts as a point.
What you enter
- A: greatest diameter (cm)
- B: diameter perpendicular to A (cm)
- C: number of slices x slice thickness (cm)
How this is calculated
- Formula
- volume (mL) = A x B x C / 2 with all three orthogonal CT diameters in cm; C is the vertical extent (measured or slices x slice thickness).
