    Additional information

    Of the 118 patients evaluated, 83 (70%) were deep hemorrhages, 21 (18%) were lobar, 8 (7%) were brain stem, and 6 (5%) were cerebellar. The correlation between measurements by planimetric and ABC/2 methods was very high (R2=.96). Measurements by a single reader using the ABC/2 method correlated well with planimetric measurements for all hemorrhage locations.
