How Analyze was Used
“Hematomas with a threshold between 44 and 100 HU were segmented using semiautomated planimetric analysis by Analyze 14.0 (Analyze Direct Inc, Overland Park, KS). Then, hematoma volume and hematoma density, defined as mean HU of hematoma, were calculated. The volume of intraventricular hemorrhage was excluded. The growth of hematoma more than 6 ml or relatively more than 33% compared with the baseline hematoma was defined as HE. Hematoma volumes in all CT scans taken within 72 h from onset were measured and used to define HE. Small ICH was defined as a hematoma volume not exceeding 10 ml; the ICH with a hematoma volume ≥ 10 ml was categorized as a large ICH.”
