ABC/2 hemorrhage volume
Bedside estimate of intracerebral hemorrhage volume from CT.
Inputs
0 of 3When to use
- Estimating ICH volume for the ICH score or trial criteria.
Pearls and pitfalls
- A: largest diameter; B: perpendicular diameter on the same slice; C: number of slices with hemorrhage × slice thickness (count slices with 25–75% as half).
Why use
Fast and well correlated with planimetry.
Volume (mL) = A × B × C ÷ 2 (cm)
