Results for 200 artificially generated brain slices with lesion. (a) Average errors for hemisphere comparison method, SLICE method, and Lasso tracing method were 1.5±1.3, 0.2±0.4, and 0.2±0.4 (mm2), respectively. (b) The corresponding normalized errors were 509±999, 14±18, and 15±20 (%), respectively. Both the SLICE method and the Lasso tracing method were more accurate (p<0.001) than the hemisphere comparison method in estimating the lesion area, but there was no significant difference between the SLICE method and the Lasso tracing method.
