Volumetric measurement of cerebellar infarct tissue via ABC/2 formula resulting in a infarct volume of 33.3 mlA. A defined as the largest diameter of cerebellar infarction in the axial slice: 5.18 cm; B defined as the maximum length 90° to A: 4.01 cm B. C as the maximum height of the cerebellar infarction in coronar plane: 3.18 cm.

Computer-assisted semi-automatic volumetry via Brainlab for the same patient resulting in an infarct volume of 35.6mL.
A. 3D model reconstruction of infarct tissue. Region of interest in the axial (B.), sagittal (C.) and coronar (D.) plane.

Spearman correlation test between ABC/2 and computer-assisted volumetry (in ml) showing an excellent correlation (r = 0.985, CI 95% 0.979-0.990; p value <0.0001).
