Figure 1. Methods for volume of hematoma and interval change of CT: (a) admission, (b) two weeks later. On the CT slice with the largest area of ICH, the largest diameter (A) of the hematoma was measured by use of the centimeter scale on the CT film. The diameter of the hemorrhage perpendicular to the largest diameter represented the second diameter (B). The height of the hematoma was calculated by multiplying the number of slices involved by the slice thickness, providing the third diameter. The three diameters were multiplied and then divided by 2 (AxBxC/2) to obtain the volume of ICH (this formula was validated by Kwak et al.).
