Hemorrhage volume is a powerful predictor of 30-day mortality after [[spontaneous intracerebral hemorrhage]] (ICH). We compared a bedside method of measuring CT ICH volume with measurements made by computer-assisted planimetric image analysis.

The formula ABC/2 was used, where A is the greatest hemorrhage diameter by CT, B is the diameter 90 degrees to A, and C is the approximate number of CT slices with hemorrhage multiplied by the slice thickness.

The ICH volumes for 118 patients were evaluated in a mean of 38 seconds and correlated with planimetric measurements (R2 = 9.6). Interrater and intrarater reliability were excellent, with an intraclass correlation of .99 for both.

Kothari et al., conclude that ICH volume can be accurately estimated in less than 1 minute with the simple formula ABC/2
