A precise, simple, convenient and new method for estimation of intracranial hematoma volume–the formula 2/3Sh

Abstract Objectives: The formula 1/2abc was a relatively reliable technique for the estimation of mostly intracranial hematoma volume, but its accuracy was prone to be affected by some particular shapes of hematoma, such as multinodular, separated and so on. In this work, we aimed to validate a more accurate method for the estimation of intracranial hematoma volume, which were free limitations of axial slices shapes. Methods: We investigated the computed tomography (CT) scans of 186 patients with intracranial hematoma. The volume values of 186 intracranial hematomas were respectively assessed using five different methods. Results: For the formula 2/3Sh, the excellent correlation coefficient obtained using Pearson and Spearman's coefficients were 0.990 and 0.990, respectively. Meanwhile, the estimated intracranial hematoma volume using the formula 2/3Sh was fairly precise, with a 0.05) underestimation. However, the intracranial hematoma volume values were estimated by the formulas 1/2abc...
