How Analyze was Used
“A semi-automated seed growing algorithm in Analyze 12.0 (AnalyzeDirect Inc., KS, USA) was used to measure hematoma and infarct volume on FLAIR images by a single rater. The rater selected a seed point within the infarct and a region-growing algorithm automatically expanded the seed points within the 3D space of the image. Manual editing was implemented when automated segmentation was not possible due to incongruent infarcts or if there were unclear lines of shape distinction with voxel intensities. For illustration purposes, all hematoma and infarct volumes were registered to the MNI brain template.”
